utils.get_queryset_and_model breaks if Model contains a field named "model"

[GoogleCodeExporter]

My model, "Server", contains a field called "model". Since this function
checks for the "model" attribute to determine if the object is a Queryset
it breaks.
A simple switch of the statements should work fine.
