Dirk Hohndel edac07554c Make sure we don't create multiple dive sites with the same uuid
This shouldn't happen, but in case there is a logic error higher up in the
code somewhere, this will prevent it from happening, period.

If the code asks for a new dive site with a specific uuid, simply return
the existing dive site with that uuid.
