switch `gracket`-based DrDr tests to `raco test -m --fresh-user`

Various GUI (especially DrRacket) tests have used `(gracket *)` as
a signal that the tests must be serialized, but those tests can run
concurrently if run with a different "home" directory (as determined
by the `PLTUSERHOME` environment variable).

Change those test to use `raco test -m --fresh-user`, instead,
which runs the test with a fresh home directory.

scribble: recognize 'exact-chars even when a style name is #f

Patch from Tero Hasu.
allow `expand` on cross-phase-persistent modules

Previoulsy, `expand` mode explicitly disallowed cross-phase declaration
in commit 2e652fc2b3. I'm not sure why, and that commit has no test
case that fails when the restriction is removed, so my best guess is
that it was a debugging strategy that I forgot to undo.
fix switch of `gracket`-based DrDr tests

Forgot the `*`, so the tests were not run.
