Modifiers: Fix bug where UVWarp Modifier would try to get bone matrix from a non armature object

There is a bug where the UVWarp modifier will stop working if an armature bone is set as the Bone To target and then later changed to a non armature object without clearing the Bone To string property. The modifier will still think it is needing a bone matrix and not properly use the object matrix.

A simple fix by adding a check for the object being an armature as well as the bonename string being set.
