templater: drop global exception catcher from runfilter() (API)

Now all built-in template filters declare input data types or handle type
errors by themselves.

   Template filters should declare input data type and/or catch
   AttributeError, ValueError, TypeError, etc. as needed. See the doc of
   ``registrar.templatefilters`` for details.
