Editing an track in import view triggers Undo to be possible

[NeoCoderMatrix86]

Describe the bug
Editing an track in import view enabled undo to be possible, while pressing undo is not making the changes back.

To Reproduce
Steps to reproduce the behavior:

1. Go to import view and import a textfile
2. Select a track
3. Edit nothing, click Cancel
4. See Undo beeing enabled

Expected behavior
Undo and redo should be possible in import view.

TODOs:

• Add undo/redo tracking of analyzed import
• Remove undo/redo when import data are reanalyzed (like changing text or profile)
• Remove undo/redo when import data are imported

Currently import is not tracked. Adding the analyzed import to be tracked is needed.
