[GNC] V3.3 on Ubuntu 18.10 can't Save As over existing mysql database

[Colin Law]

I believe that on early 3.x versions that it was not possible to Save
As on top of an existing database of the same name.  I thought that
had been fixed in or before 3.3 but I note that it still fails using
3.3 from the Ubuntu 18.10 repository.  Also I cannot find a bug
referring to the problem.

Can someone elucidate?
