Adds `80.sql` to delete rows including notification types which are not exist.
Adds `80.sql` to delete rows including notification types which are not exist.

Cause:
`PULL_REQUEST_REVIEWED` and `PULL_REQUEST_UNREVIEWED` is united to `PULL_REQUEST_REVIEW_STATE_CHANGED` on 59594601dfde26c5172b862c406d28acdb3f643e.
But rows getting these event types are not removed on `user_project_notification` table.

Solution:
On Ups, these are removed and `PULL_REQUEST_REVIEW_STATE_CHANGED` is added with `TRUE` for `allowed` column.
On Downs, all rows which contain `PULL_REQUEST_REVIEW_STATE_CHANGED` will be removed. And rows with `PULL_REQUEST_REVIEWED` and `PULL_REQUEST_UNREVIEWED` are added and set to `TRUE` for `allowed` column.
