  <!-- You can erase any parts of this template not applicable to your Pull Request. -->

  ### Description

  Currently the way `ExternalReserves` functionality is written, it can only be used with `electrum` feature. The tests should fail if the implementation behavior is enforced.. Disabling the tests in CI.

  Also removing the `regtest-esplora` features from the tests, because they won't work when bitcoindevkit#92 lands.
