Slip mode handles loops not correct

[JoergAtGithub]

Bug Description

• play a track
• engage slip mode
• set and enable a new loop
• stop the loop after some iterations
• disable slip mode

=> Play position should jump to the position where the track would be without the loop - this is the case with 2.3 but not with 2.4

I'll take a look asap.
If I can't fix it in time we need to roll back the last two commits of #11435, i.e. restore 2.3 behaviour at the cost of not fixing #6993
