LGTM: raise handle_not_found()

Turn calls "handle_not_found()" into "raise handle_not_found()" to
indicate control flow chance. It makes the code easier to understand,
the control flow more obvious and helps static analyzers.

It's OK to raise here because handle_not_found() always raises an
exception.
