fix(tables): reset the announce latch when leaving a table

The tableId cleanup dismissed the notice on departure but left the latch
holding that table's id, so returning before another table announced — a quick
there-and-back, or a second table that never loaded — found the latch matching
and stayed silent. Leaving ends the visit, so clear the latch with it.
