I'd like to fix the error reported in #13167. The main bug
{{{
#!python
from django.template import Context, Template
Template('{{ foo|default:notreal }}').render(Context({'foo': ''}))
}}}
still raises `VariableDoesNotExist` exception, which is completely
unexpected from templates, as noted in closing comment
ticket:13167#comment:20. I took me more than an hour before I found out
how did it make the server error I investigated.
I know the original ticket was closed as wontfix, but I understood it was
due to the effect the proposed change would have on `if` tag. But there's
another way - capture the exception in `VariableNode` the similar way
`UnicodeDecodeError` is silenced. If I understood the code correctly, that
would solve the problem for all template filters, but left template tags
intact.
