ZODB Components: List of migratable 'Module Components' in Products.XXX.*...

ZODB Components: List of migratable 'Module Components' in Products.XXX.* should include any kind of objects and not only modules.

This fixes Products.ERP5VCS.Git module not being displayed because
Products.ERP5VCS.__init__ only imports one of its class and not the whole
module (and the module was not imported anywhere else too) so it was not in
Products.ERP5VCS.__dict__.
