Fix T53638: View layer renaming crashes 2/2

This fixes renaming the view layer via Python.

This bug was introduced originally in 3a95bdfc65d. Although I suspect it was
around for longer, since this commit didn't touch this part of the code.

But basically we need the id of the RNA property to be the one that owns
the data (view layer).
