When going from EDIT to OBJECT mode, Blender updates the object data from the edit-mode data. This took care of renaming FCurves that animate Curve control points when control points are added/removed, but this didn't keep the FCurve groups intact. Since the FCurve groups are tightly connected to the Action channels, it's hard to keep the group pointers intact during this process. Instead of making the code even more complex in an attempt to do that, I implemented a function (`BKE_action_groups_reconstruct()`) that rebuilds the group channel pointers. The call to `action_groups_add_channel()` had to be removed because it updates the the next/prev pointers of the FCurve while we're looping over them, causing infinite loops.
