Test for different methods in `ProjectDefinition >> #postLoadJavaHook` This commit just changes the clumsy test for compiled class libraries to use multiple different methods. `#classNamesAndAttributes` may be missing in (pure) Pharo `PackageManifests`. `#mandatoryPreRequisites` may be missing in some old project definitions created before (single) `#preRequisites` have been split to `#mandatoryPreRequisites` and `#requiredPreRequisites`. Sigh.

# make uses this file (Makefile) only, if there is no
# file named "makefile" (lower-case m) in the same directory.
# My only task is to generate the real makefile and call make again.
# Thereafter, I am no longer used and needed.
