Remove unused variable

The tempurl functional tests would fail if you put tempurl.methods in
the proxy server's disallowed_sections. The test assumed that the
presence of the key 'tempurl' implied the presence of the subkey
'methods', but since 9cbf8a3 landed, operators can remove arbitrary
things from /info.

Normally I'd just change x['methods'] to x.get('methods', []), but it
turns out this was setting up a class variable that nobody ever looked
out again, so removing the code also works.
