After installing plugin the default keystore does not work due to missing password

[dfordivam]

If a plugin is installed which does not need a password, the ckb-cli does not prompt for password for the default keystore.
So most of the commands stop working for the default keystore account.

The logic of this API should be fixed to decide the password requirement based on the keystore being used (default or plugin)

ckb-cli/src/plugin/manager.rs

Lines 227 to 231 in 6622443

	pub fn keystore_require_password(&self) -> bool {
	self.actived_keystore()
	.map(|(_, _, require_password)| require_password)
	.unwrap_or(true)
	}

	Err(message) if message == ERROR_KEYSTORE_REQUIRE_PASSWORD => {
	let password = read_password(false, None)?;
	let request = KeyStoreRequest::DerivedKeySet {
	hash160,
	external_max_len,
	change_last,
	change_max_len,
	password: Some(password),
	};
	self.call(request)?

It will actually try to read password when the error message from builtin keystore is keystore require password (kind of hack)

The mistake is some cases not covered.
