xhgui-mongo database is not deleted when addon is removed

Comment by @rfay in #5 (review)

I note that the volume for the mongo stuff (ddev-d10_xhgui-mongo) doesn't get deleted when the add-on is removed (but it would on ddev delete I think). That might be a thing to do in a follow-up.

There's also a related problem. If you have xhgui running (and the mongo service), and you remove the add-on, the mongo service container doesn't get stopped, leading to a variety of problems. (And of course the volume can't be removed until that's stopped anyway)

Perhaps we have to force a ddev stop before finishing the removal? Not sure. Or we have to insist on the project being stopped before removal?

Fixed with #22

The addon now uses default project database.
