Activity parameter group not deleting properly with database

[MaximeAgez]

Seems like the group_table table of the parameters.db database is not reset properly when deleting a database through AB.

To replicate:

• Make an empty "test" database (only biosphere in there)
• Create a "testing" database with a single "test_act" activity in these where there are activity parameters used and also simple formula used (as shown below)

• Delete the testing database through AB
• Go check the group_table table of the parameters.db database. The test_act_... group previously created for the calculation of formulas in test_act is still there:

I think not having it erased alongside the database creates issues when re-downloading databases through Excel (I'm not 100% sure though), because only one group of activity parameters can exist per activity.
