fix(android): KeyStore.load takes a LoadStoreParameter, not an Object

The one-argument overload is load(LoadStoreParameter). Declaring JObject made the bridge look for a method that does not exist - reported at runtime as 'method not found', with nothing at compile time. Same class of mistake as generateSecret earlier: the JNI signature is built from the declared types, so an approximate type is a silent break.
