Bug 411452 - Search dialogue isn't "reusable" when using GTK 3.x

Hack for GTK3 in order to not get cellDataFunc while clearing as it
calls it for each row-deleted and this causes AAIOB in getId as items
are already cleared but the model is not yet.
By disconnecting the model from the handle while clearing no
intermediate signals are emitted.
