Renaming: Fix renaming in the list view being canceled when the

keyboard layout changes.

Using ibus for keyboard layout/ime changes causes a brief focus
loss when switching layouts, causing an active renaming operation
to be completed early. Block the cell-renderer's focus-out handler
and remove our own. We still get correct behavior thru explicit
selection changes in the view or enter/escape.

Fixes #3697.
