Need to check all calls to project.equals() for correct behaviour.

After fixing JRA-20038, Projects in the cache will be updated a lot more often.
This has turned up a problem where it is usually invalid to compare two project objects with project1.equals(project2)
This is because this checks ALL fields including the counter field which is constantly updated.
This equals compare can now return false for two project objects that actually represent the same project.

This problem exists for comparing Project GenericValues as well as ProjectImpl objects.
