[test] fundrawtransaction: lock watch-only shared address
self.nodes[0] creates an address which is watch-only-shared with self.nodes[3]. If nodes[0] spends the associated UTXO during any of its sends later, the watchonly test will fail, as nodes[3] now has insufficient funds. Note that this also adds a new find_vout_for_address function to the test framework.
