[#54597932] [bs-273] Circular view reference for /error
Tweak travis again
Add default /error view for HTML clients

* Add integration tests for /error view
* Add "error" @Bean as default view for HTML

Users may see side effects because now there will be

first time in a vanilla Actuator app. Should be
interesting.
