[WIP] Close all handles during Jest teardown

WIP because there's currently a `yalc` local dependency which will be
replaced once comit-network/comit-js-sdk#176
is merged and `comit-js-sdk` is released with its changes.

We ensure that all nodes are stopped and all wallets are closed during
Jest teardown.
