$transaction does not return a value for interactive transactions

First of all, thanks for this amazing library.

One issue I've noticed is that $transaction doesn't return a value for interactive transactions. I believe this could likely be remedied by just adding a return statement to line 186 to return the results of await actions(client) call.
