The incoming transactions controller now uses the `chainId` for the
current network instead of the `networkId`. This ensures that custom
RPC endpoints for the built-in supported networks do correctly receive
incoming transactions.
As part of this change, the incoming transactions controller will also
cease keeping track of the "last block fetched" for networks that are
not supported. This piece of state never really represented the last
block fetched, as _no_ blocks were fetched for any such networks. It
been removed.
The `metamaskNetworkId` property in the `txMeta` for incoming
transactions was incorrectly set as a Number instead of a String. This
change was made accidentally as part of #8627.
As a result incoming transactions were being excluded from the
transaction list, as they didn't have a matching network ID.
`metamaskNetworkId` is now set to a string, and a migration has been
added to ensure `metamaskNetworkId` is converted to a string for any
incoming transactions in state.
The `_fetchAll` function is expected to return values, so catching
errors and logging them only results in an additional error at the
place where `_fetchAll` is called. It's better instead to let the
error get thrown as normal.
In this particular case `_fetchAll` is only called in once place. The
error is still correctly caught and logged (in the `_update` function)
* Fix styling of `.transaction-list`
* Filter `incomingTxListSelector` by network as well
* Start and stop block tracker polling in incoming tx controller
* Add fetch with abort in bg for `IncomingTxController`
