Replace PrintException with PrintExceptionContinue + throw

Just a pet peeve.

(PrintException has exactly the same body as PrintExceptionContinue but
does a re-throw at the end. Move these re-throws to the call
site, this aids understanding what is going on as well as eliminates a
bit of code duplication in util.cpp)
