fix: end a tab drag when the card is disconnected

Review CODE-REVIEW-220-r2/r3, F1.

The M1 fix installs window listeners for the length of the gesture, and
disconnectedCallback — which takes down everything else, down to the other
local gesture — did not take those down. Losing the card mid-drag (Lovelace
rebuilding its tree, the user leaving the view with the button still down)
left them alive: the closure holds the instance and its config, and the next
pointerup anywhere on the page would have an invisible card write its order.

The smoke now holds a tab, removes the card, and checks that the release it
should no longer hear changes nothing. Registered as a mutant too.
