GeoGebraCASIntegrationTest:

Added beforeTest method to clear all defined variables, function names, et cetera, ahead of every single test.

Add self test tests to ensure defined objects (as above) are remembered during a test, but forgotten ahead of the next test.

Reformatted entire CASIntegrationTest - please refer from deleting (especially via autoformat) double blank lines distinguishing
sets of similar test cases from each other.

Moved some things around and improved readability.
