fix(core): Fix migrations on non-public Postgres schema (#3356)

* 🐛 Fix UM migration

* ⚡ Account for schema in `search_path`

* 🔥 Remove unneeded schema refs

* 🧪 Account for alt schema in DB testing

* ⚡ Add schema to `IncreaseTypeVarcharLimit`

* ⚡ Set `search_path` in every migration

* ⚡ Set `search_path` in down migrations
