Bump code coverage in forms
Looking at https://hyteg.pages.i10git.cs.fau.de/-/hyteg/-/jobs/684751/artifacts/coverage/coverage.html it seems that we should probably write/augment 1-2 tests so that all *epsilonvar*
and *epslioncc*
forms are at least executed once. This would cover roughly 10k - 20k lines of 150k atm.
