get_user_home test fix for django 1.6

In django 1.6, the django.utils.html.strip_tags method no longer
calls force_text on the object passed in.  This causes a
get_user_home test to fail as it attempts to concatenate the User
object and a str and fails.  Changing to a method that will take
an Object.
