Fixed one typo in response_helpers which caused is_admin context variable not to work correctly.
Created new checkLinkNameForId function that checks if link_name is correct when creating new user and modifying existing one. This is now used for validation instead of doesLinkNameBelongToId in UserForm clean_link_name function. The previous validation function didn't allow to create new users and modify linkname of existing ones. Additionally I created new doesLinkNameExist helper function.

image = models.FileField(upload_to=tempfile.gettempdir())
# Support code for the tests; this keeps track of how many times save() gets
# called on each instance.
def __init__(self, *args, **kwargs):
super(Photo, self).__init__(*args, **kwargs)
self._savecount = 0
def save(self):
super(Photo, self).save()
self._savecount +=1
