Controller loading State

[korgon]

There exists a condition whereby the controllers can get locked into a loading: true state. This state is set when the beforeSearch event kicks off, and typically is set to false when the afterStore event concludes. In the SearchController, the loading state never returns to false when the following return takes place:

However, I am pretty sure that this return would also leave the controller in a similar state:
https://github.com/searchspring/snap/blob/v0.61.5/packages/snap-controller/src/Search/SearchController.ts#L344

There is a "catch" block below that does set the loading state back to false when errors are caught, but that does not happen in the cases above.
https://github.com/searchspring/snap/blob/v0.61.5/packages/snap-controller/src/Search/SearchController.ts#L530

The other controller types likely have similar issues. We should ensure that when a search cancels, errors out, or is prevented that the loading state is properly set back to false. Testing should be improved around these situations to validate that we have the proper state (loading: false).
