Subject: [PATCH] [key-manager] check if the key is present before exporting
 the key (#9814)

While trying to read the Pskc or networkkey, we check if the keyref is
valid. We instead need to check if the key is present. There is a
possibility that the persistent data was erased before trying to read
the key, which might result in asserts.
