fix: error on first custom provider deletion (#1110)

fixes #1109 https://github.com/WiseLibs/better-sqlite3/blob/master/docs/api.md#transactionfunction---function > Transaction functions do not work with async functions. Technically speaking, async functions always return after the first await, which means the transaction will already be committed before any async code executes.  --- ## Summary by cubic Fixes a runtime error when deleting the first custom provider by using a synchronous DB transaction. Ensures associated models and the provider are removed atomically without failing. - **Bug Fixes** - Replace async transaction callback with a synchronous one and remove awaits on tx operations to match the DB API and prevent the first-delete error.
