[BUG] Fix for module endpoints using alternate ID

The endpoints for fetching modules and module definitions
previously returned empty result if a CM handle was not
found or not ready. Recent changes for alternate ID have
changed the behaviour so it returns an error instead.
This restores original behaviour by swallowing the exception.
