PostSync hook not happening on auto sync multiple paths

• I've included steps to reproduce the bug.

Describe the bug

After an upgrade to ArgoCD 2.13.0, we noticed our PostSync hook no longer triggering on automatic syncs, if you do a manual sync it does still trigger.
Our setup is a mono repo with all config files and different paths for different applications, the PostSync job reports the state back.

To Reproduce

• Create two applications with the same repository and different paths.
• Create a PostSync job in the first path, do not create one in the second.
• Update the second path, since the release SHA is different, both apps will sync. App 1 will have no changes though.
• Sync app 1 manually, the PostSync job runs.

Expected behavior
In the past, because app 1 synced, the PostSync job was run.
We expect this behaviour to still happen.

Since this is maybe a bit of an edge case, maybe have an option to enable hooks when no actual changes occur in the application.
