[analyzer] Plist diagnostics: Fix a case where we fail to close an XML tag.

If the current path diagnostic does /not/ have files associated with it, we
were simply skipping on to the next diagnostic with 'continue'. But that
also skipped the close tag for the diagnostic's <dict> node.

Part of fixing our internal analyzer buildbot.
