Fix infinite loop in expander

* module/ice-9/psyntax.scm (resolve-identifier): There is a case where a
  syntax object can resolve to itself.  Prevent an infinite loop in that
  case by continuing to resolve by name.

* module/ice-9/psyntax-pp.scm: Regenerate.

* test-suite/tests/syncase.test ("infinite loop bug"): Add a test.
