Move SanitizePads to CLIENT_SELECTION_FILTER architecture.

This not only reduces the number of different mechanisms, but
will also reduce (yet again) the number of Clarify Selection
pop-ups (because the CLIENT_SELECTION_FILTER runs before the
pop-up, while SanitizePads ran after it).

Fixes: lp:1710451
