Description

After deleting a repo the times API has become unusable:

$ curl -X GET "https://bobemoe:xxxx@try.gitea.io/api/v1/user/times" -H  "accept: application/json"
{"message":"issue does not exist [id: 9010, repo_id: 0, index: 0]","url":"https://try.gitea.io/api/swagger"}

I've checked the DB and indeed the issue records for the deleted repo have been deleted but there are still records in the tracked_time table that now have a non-existent issue_id:

mysql> select t.*,i.id from tracked_time t left join issue i on t.issue_id=i.id having i.id is null;
+----+----------+---------+--------------+-------+---------+------+
| id | issue_id | user_id | created_unix | time  | deleted | id   |
+----+----------+---------+--------------+-------+---------+------+
|  3 |     1361 |       1 |   1571125831 |  3600 |       0 | NULL |
|  4 |     1361 |       1 |   1571125838 |  1500 |       0 | NULL |
....

so on repoDeletion we have to delete tracked_time too

This issue has been automatically marked as stale because it has not had recent activity. I am here to help clear issues left open even if solved or waiting for more insight. This issue will be closed if no further activity occurs during the next 2 weeks. If the issue is still valid just add a comment to keep it alive. Thank you for your contributions.
