Ability to edit/remove already tracked issue time

[xak2000]

Description

It should be possible to edit or at least remove already tracked time.

For example:

• I can accidentally track wrong number (80h instead of 8h).
• I can forget to press "stop" button after "start" and remember this after two weeks.

And it should be possible to undo this or change these tracked values, or else it would be to dangerous function to use.

I think that this is a duplicate of #2642.

I can forget to press "stop" button after "start" and remember this after two weeks.

You could click on the "Cancel" button the abort the timestracking stopwatch.

You are right, #2642 is the same.
