LibSQL+SQLServer: Do not re-open databases

Browse source 
Both `Database` and `Heap` were allowed to be opened twice. Prevent
this, and change SQLServer to only open databases that are not already
opened.

This fixes a Ladybird crash where opening the application twice would
erroneously duplicate free heap block indices.
