Pull request description:

  ### Description

  `TestEnv` is extracted into its own crate with `electrsd` support added so that `TestEnv` can also serve `esplora` and `electrum`.
  The tests in the `esplora` crate have also been updated to use `TestEnv`.

  The `tx_can_become_unconfirmed_after_reorg()` test in `test_electrum` suggests that the electrum issue where a reorged tx would be stuck at confirmed does not exist anymore.

  ### Notes to the reviewers

  The code for `tx_can_become_unconfirmed_after_reorg()` was adapted from the same test in `bitcoind_rpc/test_emitter`. This electrum version of the test requires extra review, as I am uncertain if I used the API efficiently.
