This fixes up the rest of the broken javascript unit tests. There were two

issues:
1. The way that the bug tracker links are formed has changed significantly.

   The old test was sufficient for determining that the alternate formatting

   was being used, but because of the new redirect URLs, the contents of the

   comparison had to change.

2. The signature of the 'destroy' signal had changed, and the comparison

   was no longer succeeding.

Ran js-tests in firefox.
