Disabling a repo doesn't remove CRON builds

Component

server

Describe the bug

When disabling a repo, the id in the repos table is set to 0. However, existing CRON tasks defined in the repo are not altered in the crons table.

The server is trying to execute them normally and fails in the logs with

Whether or not the CRONs should be deleted is debatable (likely not so they continue to work in case the repo gets enabled again). Yet then they should gain a new column which indicates whether they are active or not.

The following DB query can temporarily clean up (= delete) CRON jobs of deactivated repos:

DELETE FROM crons
WHERE repo_id IN (
    SELECT id
    FROM repos
    WHERE user_id = '0'
);

This could also be part of a daily "garbage collection" job.

Steps to reproduce

Define CRON
Disable a repo
Inspect server logs during execution

Expected behavior

CRONs are disabled/not run when a repo is disabled.
