Merge lp:~edwin-grubbs/launchpad/bug-567065-empty-branch into lp:launchpad

[Edwin Grubbs]

Summary
-------

The "Submit Code" link in the involvement portlet on a product series
should be active after the user sets a branch for the series.

If you try to create a new branch with the same name as an existing
branch, you should get a warning.

Tests
-----

./bin/test -vv -t 'productseries-setbranch-view.txt|productseries-views.txt'

Demo and Q/A
------------

* Open http://launchpad.dev/firefox
  * Create a new series.
  * The "Submit code" link should be disabled.
  * Use "Configure series branch" link to add a new branch.
  * The "Submit code" link should now be enabled.
* Click on "Configure series branch".
  * Try to add a branch with the same name as the one you just created.
  * You should get an error message next to the form field.
