"Force Keeping channel for objects" inserts undesired keyframes for Armatures

[The0Dev]

Describe the bug Hello. When I export a scene with the "Force Keeping channel for objects" option enabled, armature objects themselves end up having extra keyframes despite the fact that they were not animated.

To Reproduce

1. Open the attached blend file
2. Export the scene with the option enabled
3. Import it back
4. See the results

Expected behavior The armature object itself like the Cube in the same scene should not be animated (only its root bone).
