Axel Lin 3efac7b7fa mqtt_msg: Set zero length username if password is set without username ...

Some cloud server (e.g. exosite) takes empty username with password.

When password is set without username, the current esp-mqtt implementation will
ignore the username and only set password. This violates MQTT-3.1.2-22 [1].
To address this issue, send zero length username if password is set without username.

[1] MQTT-3.1.2-22: If the User Name Flag is set to 0 then the Password Flag MUST be set to 0.
