Ability to create custom result tabs is broken in the gui.

When a plugin developer creates a custom result tab following the available documentation, the gui is broken when switching between jobs. The url is not properly updated when query strings are used for custom actions. The javascript used to update the links in the Plan Navigator assumes that the url will contain the buildResultKey ($plankKey-$buildKey-$buildNumber) but this is not the case when using query strings which take the form of buildKey=${buildKey}&buildNumber=${buildNumber}.
