Split signrawtransaction into wallet and non-wallet

Splits signrwatransaction into a wallet version (signrawtransactionwithwallet) and
non-wallet version (signrawtransactionwithkey). signrawtransaction is marked as DEPRECATED
and will call the right signrawtransaction* command as per the parameters in order to
maintain compatibility.

Updated signrawtransactions test to use new RPCs
