[Feature/Bugfix] Tagtree use insert context to speed up adding tracks to playlist

I forgot we had duplicated code between playlist.c and tagtree.c this saves
a bit of space and should speed up adding tracks a bit

further I noticed a buf here where there was the potential to return without closing
the opened track search
