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.

The notification comes from another repo with same branch name:
