fix(wallet)!: delete method insert_tx

Inserting unconfirmed txs can be done using the existing method
`apply_unconfirmed_txs`. Also removed `insert_checkpoint`, as the
API is unclear regarding where in the local chain the given block
should connect. Analogs for these methods are found in `test_utils`
module and are mainly used to facilitate testing.
