[libgdx] Fix track 0 dip mixing to animation with key > frame 0.

Browse Source 
Repro:
1) Open: https://n4te.com/x/3415-test.spine
In Preview:
2) Options, show bones.
3) Disable looping.
4) Play animation 1.
5) Set mix to 1 second.
6) Play animation 2 (key > frame 0).
Expected: 1 to hold, then 2.
Result before fix: 1 dips toward setup pose, then 2.
