In 8278b763d9 the default behaviour of annotation
has changes, which was causing a lot of noise in diffs. We decided in #17382

look at schema.rb for the columns in a table.
Fixes: #17382
* visiting project will create notification setting if missing
* change notification setting per project even without membership
* use notification settings instead of membership on profile page
