Pump up some deps

Needed to pump the lightning version used and had to pump bitcoin, bitcoincore-rpc aswell to match dep verions in lightining
merkle root computation changed in `bitcoin`, thus some methods in the test_utils needed to adapt (basically by adding a tx if there is none in a block). See: rust-bitcoin/rust-bitcoin@b454cf8
Also SecretKey had it's `to_string` method removed, so TEOS now encodes its tower key using `secret_bytes()` and `from_slice()`. See: rust-bitcoin/rust-secp256k1#312
