Description 
In the process of solving issue SCHEDULER-246,  discovered a case where unguided dithering would not have the last slew-to coordinates available. See that issue for details. Need to add logic to unguided dithering to capture the current J2000 scope coordinates as the base for dithering instead of relying on c_LastSlewRA/Dec which might not be valid. Just always use the scope coordinates, avoiding other cases where these variables may not be valid.
