a9b9ca82da gui: ensure external signer option remains disabled without signers (Andrew Chow)
Pull request description:
When no external signers are available, the option to enable external signers should always be disabled. However the encrypt wallet checkbox can erroneously re-enable the external signer checkbox. To avoid this, CreateWalletDialog now stores whether signers were available during setSigners so that future calls to external_signer_checkbox->setEnabled can account for whether signers are available.
