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

Browse Source 
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.
