Allow pasting references to mathed

Browse Source 
A reference can be directly inserted into mathed but cannot be pasted
because the pasted material is returned in plain text format. This patch
allows getting a string from the cut stack in a suitable format allowing
the math parser to actually create an InsetRef.

Fixes #11539
