Fix T77448: Camera Solver constraint can't be converted to f-curve

A regression caused by c57f65c088a9 as a fix of another issue.

Added an exception for camera solver as that is always pointing
to camera object.

Since this is a regression which happened in 2.83.0 this change is
a candidate to be ported to the 2.83.1.
