Fix empty password save behaviour on settings. 

The earlier logic for copying existing passwords from the DB to
SMTP and messenger settings when the frontend sent an empty
password was based on array positions (and flawed). This commit
introduces an internal UUID field to SMTP and Messenger settings
to keep track of password changes in the settings UI.
