The fromURL methods for korrel8r query conversion correctly throw errors when failure occurs so that failure reasons can be displayed. However, in the useURLState hook the function is not wrapped in a try/catch block, leading to an uncaught error. This is most apparent in the alerts detail page in the developer mode where the URL state is not in the expected format and so errors causing the page not to load.

This fix should prevent an uncaught error and also prevent the panel from appearing in the Alert Details page of the Developer View.
