getSemanticDocumentHighlights: don't fail...

Browse Source 
...when missing `program.redirectTargetsMap` info.  This assertion fails
in the added test case -- looks like there is no entry in
`program.redirectTargetsMap` when it comes from a file that is no in the
project.  So in this case don't follow the (missing) info, and instead
drop the highlight.

Fixes #33722.
