Excising data from Database does not notify of removal like Retract would

[Al12rs]

This was noticed due to Logout not updating the UI correctly. The code was changed to use Excise rather than retract.
Excise seems to not be notifying of changes, like retract does.

Excise should notify of removals, like retract does.

Additionally, Excise seems to be a standalone operation that does not go through transactions and Commit, which is a departure from the current API.
It would make sense if Excise worked consistently with the other DB operations, going though a Commit.
