Fix control line edit crash when undoing history

Browse Source 
When perspective control line editing is active and the history entry is
changed such that edit mode is automatically disabled, there is a crash.
The history change triggers a processing parameters update and disables
editing. When editing is disabled, the perspective tool also tries to
update the processing parameters, causing a double mutex lock attempt.

This commit avoids updating parameters from the perspective tool and
uses the tweak operator (introduced with the spot removal tool) to achieve
the same effect.

Closes #6251.
