- Moved some methods from Transactor to users of it to clean interface.
- Mocked Bridge interface and Transactor interface for tests
- Wrote unit tests for SendTransaction
- handling `null` values in the Hop response
- using data returned from the Hop api when preparing data for estimation and calling `swapAndSend` and `sendToL2`
- estimating gas for bridges implemented in the bridges implementation types, avoiding wrong gas for placing bridge transactions
Reading the Nonce from the local cache may be incorrect if the tx is made out of the Status app or
if Status app sends a tx prepared by the dapp (via WalletConnect). A submitted tx with a wrong Nonce
results in a failing tx, that's why we need to read the Nonce from the network.
This functionality is needed in case the user wants to send a transaction and
signs it using the signature provided by the keycard (or any other compatible way).
