Fix exception when remoting from Windows to non-Windows (#760)

Checking for DSC capability is currently done by attempting to import
a drive qualified path to where we would expect the DSC module. This
fails during parameter validation due to an invalid drive.

This change broadens the scope of the catch block to account for this
exception.
