Ensures that `hideLoadingIndication` is always called in all actions that call `showLoadingIndication`. It's unclear how many of these actions were failing to hide the loading indication, because other actions superset `hideLoadingIndication`.
At the very least, `updateTransaction` was probably failing to hide the loading indication in the error case.
This PR also refactors a lot of actions to call `hideLoadingIndication` once in `finally` blocks as opposed to multiple times across `try` and `catch` blocks. We avoided making changes to functions using `Promise` methods, because `Promise.finally` is not supported by Waterfox, and it's not properly transpiled by Babel.
