  ### Description

  fixes #1827
  replaces #1828

  I changed the `SqliteDatabase` struct to create new  rusqlite `Connection`s with [WAL](https://www.sqlite.org/wal.html) journal mode enabled and 5000ms busy_timeout. This prevents a large sync from trying to start and commit a batch (db transaction) while the initial non-batch connection is still busy writing it's data.

  ### Notes to the reviewers

  I commented out the `electrum::test_electrum_large_num_utxos` test since it takes an hour to run. Before the fix in thie PR it would also fail with only 10 large TX.

  The dev dependency and pinning changes were required to run the new, and other tests.
