alert_words: Update remove_alert_word codepath to send event on commit. 

Earlier, we were immediately enqueueing event in
'do_remove_alert_words' which can lead to a situation, if any
db operation is added after enqueueing event in future, where the
action function fails at a later stage.

Events should not be sent until we know we're not rolling back.

Fixes part of #30489.
