Create Task Error Handling and Audit Task Errors

[jue-henry]

Currently some of our errors related to async tasks are fallen to the wayside as there appears to be discrepancies between how errors are handled, particularly differences between errors when creating the async task vs errors received after the async task is completed/failed.

Ex: malform the body of the the getStats task here, then try and getStats via the button on the filter panel footer

This should cause an error to appear via the ErrorToast, but it just causes the stats page to load indefinitely, since we never see the error toast and dismiss any error
