`stub_licensed_features` does not work for groups due to memoization

Summary

Calls to stub_licensed_features sometimes don't work when testing group-level features.

The current workaround

Currently, this can be fixed by creating the group using let_it_be_with_refind instead of let_it_be.

Background

This issue is very similar to #10385 (closed). To resolve this issue, !54215 (merged) automatically patched Project#licensed_feature_available? in specs, so it was no longer necessary to use let_it_be_with_refind with projects.

Proposal

Do the same thing as !54215 (merged) but for groups: patch Group#licensed_feature_available? in specs.
