Fix resetEncryption to remove secrets in 4S (#4683)

Browse Source 
* fix(crypto): `resetEncryption` remove secrets in 4S

Remove the cross signing keys and the backup decryption key of the 4S when calling `resetEncryption`

* test(crypto): expect secrets to be deleted in 4S when `resetEncryption` is called

* test(secret storage): add test case when the secret is set at null

* fix(crypto): remove default key in 4S

* test(crypto): default key should be removed from 4S
