Fix breakage in all service repo unit tests, due to duplicate imports of exts
Duplicate imports of the same class + super() are not playing nicely
together, and our unit test base classes cause some dups in the extension
search path, breaking the service repos. This was not noticed earlier
in the extension moving process, because the temporary move code had a crude
mechanism to prevent the loading of same named extensions.
