Harmonize AF3 project builder configuration
Currently, the builder configuration is quite inconsistent.
While in most of the cases, this does not cause any problems, there are also some projects with more problematic issues:
- the EMF code generation builder is triggered after the Java builder, causing strange build errors because the Java builder only sees outdated source code
- the warnings removal builder is run before the EMF generation builder, rendering it useless in some causes
