match_regex_list indexes item_matcher[-1] to check for '$' suffix. An empty string pattern causes IndexError: string index out of range. This is reachable from CeleryIntegration.exclude_beat_tasks when user configures an empty string in the pattern list. Guard with if not item_matcher: continue before the index check.
