rpc: handle passing wallet path as 'wallet' argument

handles passing the wallet path as 'wallet' argument instead of
'wallet_path'. This did work in 4.5.8 and fails in 4.6.0 as the wallet
path string will get passed directly to the command instead of the
required wallet object, causing an exception when methods are called on
the str.
