uniquify-get-unique-names: Return a list with propertized strings

Browse source 
* lisp/uniquify.el (uniquify-get-unique-names): Return a list of
strings, and add text property 'uniquify-orig-buffer' to each,
pointing at the corresponding buffers (bug#77312).

* lisp/progmodes/project.el (project--read-project-buffer):
Look up that property's values here and build the alist.
