As a user, I want to stop the current activity WITHOUT REMOVING THE TIME VALUE so that I can switch to rest or to the next activity without waiting for the current activity timer to finish.
AS IS: when I press the arrow button to start the break before the timer ends - the whole session is deleted, if it is less then the session duration.
TO BE: when I press the arrow button to start the break before the timer ends - the whole session is recorded, even if it is less then the session duration.
