Fix Dnd from clip-picker on macOS 

On macOS, `context->get_targets ()` may be empty when dragging.
In this case the Clip-Picker assumed that a slot is about to
be dropped and switched to the local clip library.

This in turn cleared selection and it was no lnger possible
to drag any clip out of the library.
