Fix T63211: Can't move camera in viewport while realtime render mode on

The issue is that Eevee directly evaluates animation on a datablock which
is a part of active dependency graph.

This is a broken logic by design and requires a complete revamp to support
more real life cases when camera is parented to a camera rig, but it is
beyond of what i can do with a simple bugfix.
