Fix tests for oriented 2D models for new orientation defintion

Description (last modified by butler)
With the new orientation angle definitions, a number of the 2D unit tests failed to pass and were commented out. Now that we are preparing to release with the new definition we need to make sure that the unit tests are correct (i.e. that the models still work correctly).

From Richard's email
20 Dec 2016 following discussion in the tele-conference.
Looking at the .py code for each, see list below for the models that I expect to be influenced by the change of angular coordinate conventions. Dirk commented out some unit tests, which were failing after he changed the coordinate system. The coordinates were then reverted to the original method in order to allow other testing which compared sasmodels with old sasview routines. I think that Paul K has now today “switched back on” the new coordinates in the master branch, he has a single line of code which does this.
I will have a look at the three cases all in bold, as it “ought to be easy” to reinstate at least some of their unit tests. We really need more unit tests in many other models which are missing them, as there was a tendency to think when converting the models that we would “get around to that later …” and in some cases the conversion was done before the unit test system was up and running.
I don’t know if the parallelepiped models are affected by the coordinate change – perhaps someone clever can let us know please.
With hindsight I should have put this list in a table on the wiki, sorry, was not intending to write so much when I started it. Apologies for any mistakes or omissions here.

sc_paracrystal – three 1d tests, (does 2d calc, has 3 angles)
Parallelepiped Functions
core_shell_parallelepiped - two 1d tests, two 2d tests, (has 3 angles, check in new coords?)

Others
I am assuming that all “sphere” and “shape independent” functions are purely 1d.

- Milestone changed from SasView 4.1.0 to SasView 4.2.0
moving to 4.2 since assymetric orientation is getting changed in 4.2 anyway

After code camp in Grenoble, I think that all the models above that were missing tests now have some 1d and also 2d where appropriate. Beware however, that thus far these are only in the ticket-890 branch of sasmodels, see #890 and #776.
Where I did add new tests, I assumed that the current code is producing correct results. This is only particularly serious for the fcc-, bcc- and sc- paracrystal models where where the numerical calculations may still be method and/or compiler dependent, so some 2d tests may yet need to be commented out. Also of course for those models there are no ways to compare against others, unlike the various cylinder & ellipsoid models where limiting cases can be compared. (Please also when you write unit tests ensure that the numerical values of all parameters are different, so that the tests are robust if the order of parameters is later changed in say a subroutine).

There are commented out tests in the following files, some of which may be orientation tests:
