Fix wrong display of recently pushed notification (#25812)

There's a bug in #25715: 
If user pushed a commit into another repo with same branch name, the
no-related repo will display the recently pushed notification
incorrectly.
It is simple to fix this, we should match the repo id in the sql query.
