Remove parameters for createencryptedwallet.

The createencryptedwallet extension RPC request should not be used to
create wallets for additional accounts.  Instead, all btcwallet
accounts should use the same passphrase as the default account's
wallet.  This change removes the account name and description
parameters from createencryptedwallet, as it will only be used to
create the default account.
