Fix RemovedInDjango18Warning

[naringas]

RemovedInDjango18Warning: LogicalDeleteModelAdmin.querysetmethod should be renamedget_queryset.

django.contrib.admin.ModelAdmin.get_queryset

[psychok7]

@naringas instead of renaming the function why not adding it as a new function to keep backward compatibility??

If i am not mistaken if you rename this you will be breaking previous django versions

[naringas]

get_queryset is supported from django 1.6 (so this change will break django 1.5), however not having this change will break django 1.8

so, add this @psychok7?

def queryset(self, request):
    return self.get_queryset(self, request)

[jtauber]

breaking 1.5 is fine I think

[psychok7]

@naringas exactly.
