Broken examples in admin documentation

[John-Scott Atlakson]

Two examples in the ​admin doc incorrectly call .upper() on a tuple.

[Chris Beaven]

With a function called upper_case_name, the output should match. Something like:

return ("%s %s" % (obj.first_name, obj.last_name)).upper()

or probably this would be clearer:

name = "%s %s" % (obj.first_name, obj.last_name)
return name.upper()

[Malcolm Tredinnick]

Yes, Chris' first example is the intention. Otherwise the example wouldn't make sense.
