Fix issue 1900 -- multiple fret-diagram-terse markups commands crash (issue 5432081)

Reviewers: ,

Message:
I've created a patch for Issue 1900.  It solves the crash, but perhaps
in a non-optimal way.

David, will you please review this, since I've changed code that you
added to scm/fret-diagrams.scm?

Thanks,

Carl


Description:
Fix issue 1900 -- multiple fret-diagram-terse markups commands crash

This fix uses an explicit definition of the default properties for
fret-diagram-terse and fret-diagram markups, instead of copying those
from the fret-diagram-verbose markup.

No regression test will be included, since it requires a special
lilypond-book call to test.  But the Lilypond issue will have a
regression test file posted.
