deleting database with parameters breaks parameters

[marc-vdm]

Deleting a database that has parameters will break the parameters. AB should properly remove parameters that are used in the database being removed. It seems the parameters are removed from BW, but not synced to the AB table.

Users can re-set the database of the parameters and then delete them.

So, when deleting a database, AB should check whether activity parameters (from that DB) or database parameters are used, and delete them.

This check should probably happen here
