createOperations(): remove the concept of geodetic_datum_preferred_hub

This was introduced in 63857c92b271bbcd10df0a032304982011acb2a9. Due to
the fix done in the previous commit, we can mostly revert the above commit.
We just keep the added tests and the custom WGS 84<-->WGS 84 (Gxxxx) null
transformations.
