[r=jcsackett][bug=746277] Fix the retry link to request package diffs on localpackagediffs page.

This branch fixes the retry link to request package diffs so that removing the link removes all the js listeners.

== Summary ==
On the +localpackagediffs page, when a package diff fails, a retry link is displayed. The listener was not properly cleared so it seemed that the clickable zone of this retry link was far too wide. This branch refactors the way the initial link is added so that removing it clears all the js listeners.

== Tests ==
lib/lp/registry/javascript/tests/test_distroseriesdifferences_details.html

== QA ==
On a failing package diff request (https://dogfood.launchpad.net/deribuntu/dangerous/+localpackagediffs), make sure than the Retry click listener is limited to the word "Retry".

As I said in IRC, it could be worth getting a UI person to validate your decision not to have the red flash animation anymore. I think you're notion of already getting instant feedback is correct--it's your call if you think you should get UI checks on it too.

Otherwise, this looks good. Thanks.
