Spring Boot: don't generate default password during the startup

[php-coder]

Example of the message from boot log:

[2016-04-11 13:09:19.546] boot - 3346  INFO [ru.mystamps.web.support.spring.boot.ApplicationBootstrap.main()] --- AuthenticationManagerConfiguration: 

Using default security password: fe783daf-d6a6-4df7-bda5-ccf0f1c1cdce

It isn't reproducible now.
