gitea: [BUG] In 1.15.0, git push activites does not work, webhook on push not work

• Gitea version (or commit ref): 1.15.0+dev-578-g8464fa15d
• Git version:
• Operating system: official docker
• Database (use [x]):
  • PostgreSQL
  • MySQL
  • MSSQL
  • SQLite
• Can you reproduce the bug at https://try.gitea.io:
  • Yes (You edit a file commit it, this behavior will not show up in the dashboard, and if you have webhook, it will not trigger)
  • No
• Log gist: Sorry, but I dont see any error/abnormals in logs of gitea.

Description

I upgraded my gitea image to the latest version in dockerhub. And the webhook no longer works, I found that my git push activities are not presenting in my dashboard. Looks like the new version gitea totally missed my git push activities.

Action You push a commit to a repo.

Expected

• Your commit shows up in the dashboard, like below,

• The webhook of this repo will be triggered by this push

Actual

• You can see your commit in the source code page
• But your commit does not show up in the dashboard
• The webhook is not triggered

Below is my recordings about that, all I test is to push a commit into the repo, and expect this action to be shown in the dashboad, and demostrate that it works in the older version, and not working in the newest one

Git activities works in v1.14.4

Git activities breaks in v1.15.0
