Short description of error
Unable to export animation with one frame and keys not on all bones in fbx

Exact steps for others to reproduce the error

Open attached .blend file or
- Create simple armature with 2 bones.
- Set the key on only one bone in first frame.
Try to export this armature and action to fbx.

If I set Simplify to 1, I get fbx without keys at all.
If I set Simplify to 0, I get Fbx with keys on all the bones, which I don’t need.

I can confirm that the keyframe disappears, but I don't see much use in animation with a single keyframe.
Maybe it's not really a bug, but rather how FBX works.
