Remove SET CONSTRAINTS during postgres migration

Browse source 
The PostgreSQL migrations do not need this setting.
I tested this by running an old Vaultwarden instance (v1.18.0) on a new
PostrgreSQL database, created a few users and some vault items, after
that run the new code and it doesn't break.

Fixes #3930
