Subject: [PATCH 1/2] Fix #135666: Renaming a slot used by multiple IDs breaks
 animation on certain channels

The issue was that the `FCURVE_DISABLED` flag is set when an
RNA path cannot be resolved, and that skips evaluation.
However in the specific case, that is actually something expected as
the property only exists on one ID and not the other.
