Fix T101930: NLA Actions Stash remove doesn't work on overriden linked data.

Code adding stash track was clearing out track flags, instead of editing
them as it should have...

Note that there are a lot of other weaknesses in action stash code (like
relying on the (translated!!!!!!) name of the track to know whether it's
a stah or not).
