Fix test playback missing pqLineEdit changes.

pqLineEdit never ended up firing textChangedAndEditingFinished() during test
playback. To overcome that issue, we mark editing-finished as pending even when
we receive a key-event. Since tests are recorded with a return or tab key to
ensure the value gets pushed, this results in the
textChangedAndEditingFinished() fired appropriately.
