Merge lp:~rharding/launchpad/lpclient_fix into lp:launchpad

[Richard Harding]

Fix client.js to maintain uri on PATCH requests so that web_link:changed event fires off LP.cache updates.

= Summary =

Fixes bug #1004248 introduced by attempting to fix bug #911973. That fix only
considered named_post/get methods and not patch methods.

== Pre Implementation ==

Talked a bunch with Aaron and Deryck while working on issue and best way to
fix.

== Implementation Notes ==

The big fix is to only reassign the uri when the request method is not a
patch. #89 of the diff.

This required letting the wrapper method know what the method was so we pass
that along in the args.

Tests were added to verify that this is not altered during a patch, but is
during a named_get/post. See #776.

The test suite was updated to the new standard format and thus was indented
for the big line change there. No other tests were modified or adjusted.

Since the entry/resource lp_original_uri no longer makes sense, it's just
changed to uri. It's used in other methods that the instance makes so they
were updated to match.

There are a few other small drive by lints to fix spacing and such. See
#8/25/etc.

== Tests ==

xvfb-run ./bin/test -x -cvv --layer=YUITestLayer

== LoC Qualification ==
Need 54 LoC

Worked on cleaning up the client.js, removing the original bug test that isn't
required and isn't run.

Looks good.
