Filter transaction list for current blockchain network

When starting up, we now create a `web3` inside the `background.js` process, which we pass to the `idStore` and ask for the current `network`.

We include the `network` on `app.metamask.network` in the state object.

We re-request the network when changing provider.

We filter the transaction list for transactions that match the current network.
