application credential cache is not invalidated

[wangxiyuan]

application credential cache is not invalidated when the related user is disabled/deleted or the related assignment is removed.

reproduce:
1. create an application credential.
2. get it for caching.
3. delete the related user (or disable it, or remove an assigned role)
4. get it again.

Expect: return 404 in step 4.
Actual: still return the deleted application credential.
