Make tests pass with GAP 4.15

[antonio-rojas]

GAP 4.15 causes a few test failures caused mostly by different ordering of group characters and different elements returned for an_element in group algebras, make test pass with both old and new versions.

Not sure if you addressed this already, but it seems that some tests are now really slow:

By "now" do you mean with GAP 4.15? This PR only changes the expected output of some tests

Yes, sorry, I should have been more clear. The test I mentioned seems to be a lot slower on GAP 4.15 than it was on GAP 4.14. More specifically, testing src/sage/groups/libgap_morphism.py goes from 3 seconds on GAP 4.14 to at least 460 seconds (minimum of three runs) on GAP 4.15, and it doesn't seem to be seed-specific.

Indeed. I have reported it upstream at gap-system/gap#6135
