Error on testing integration if fetch fails

[jpople]

Bug Description

When clicking "test integration" on the integration configuration page, if the test operation can't connect to the server (e.g. if the backend is not running) an uncaught runtime error occurs.

Steps to Reproduce

1. View a system with a linked integration
2. Disconnect Fides backend
3. Click "test integration"

Expected behavior

Error should be caught

Screenshots

Additional context

See here for Allison's explanation of this and a possible solution. Simply removing the try/catch in datastore-connection didn't work, it still caused the error to occur on on the "connections grid" page.
