EPS/.ai import: a font is found by its exact PostScript name before the name is split

The private data a .ai file opens with names fonts by PostScript name, and
the importer split the name at its first hyphen: rounded-x-mplus-1c-black
became the family "rounded", style "x-mplus-1c-black", which no font has,
so the type fell back to Source Sans 3 although Rounded-X M+ 1c is
installed. An installed or bundled face of that exact PostScript name now
gives its own family and style; other names split as before.
