When bugs are filed, they automatically add the 'Original alerts at time of bug-filing' link to the Monorail bug. If there are many alerts (such as the case with this bug) then clicking the link gives us the dreaded Error: Bad Request. Your client has issued a malformed or illegal request. error message.

This was fixed in #2876 by allowing /group_report to use ?sid= (as is done in /report), which prevents the URL from being too long. However, this code wasn't updated to also use sid.

To fix, we need to generate and put() a new page_state for the relevant keys and link to that instead.
