#22767: Unexpected value for an unset variable with length filter in templates

Not sure if this is a bug or I'm just missing something, but I expected
this to be `False` anyway:
`{% if groups|length > 0 %}`
This will be `True` in Django 1.6.5 if `groups` is an unset variable. The
`TEMPLATE_STRING_IF_INVALID` setting has the default value (empty string).
I know it's not idiomatic code and I fixed it:
`{% if groups %}`
(which works as expected), but other newbies like me can have a hard time
figuring out what's wrong.
I checked `{% if None|length > 0 %}` and it is also `True`, which is
clearly not expected.
