Clear cache for project's licensed features in EE specs [RUN AS-IF-FOSS]

What does this MR do?

This MR patches Project (specs only) to clear its cache related to stored information about licensed features.

This allows us to get rid of workarounds such as let_it_be_with_refind or project.clear_memoization(:licensed_feature_available) in before blocks.
