Take a deleted bot out of the rail at once

Deleting a bot only changed the page after a reload. The delete route now
reads who could see the bot before removing it, since its assignments and
workspace places go with it, then pushes server:bot-removed
(BotRemovedData) to them. useLiveBots drops the row, so every tab and
every workspace the bot was in updates together.
