Cleanup code for finishing undo/redo of image operations
Summary:
D11715 introduced a function finishUndoJob() which adds a timer
delay for QUndoStack updates. After enabling redo in D12105 this
separate function for undo operations is not needed anymore and all
operation types can be handled in finish().
FIXED-IN: 18.04.2
Test Plan:
- Use different image operations to edit one or more image(s)
- Check that undo/redo behaviour did not change
