print validation errors when gitlab-rake gitlab:import:repos fails for project

Currently, when gitlab-rake gitlab:import:repos is not able to import a project it justs prints "Failed trying to create project" to the console. There seems to be no way to find out what exactly has failed. Since the check uses validation, it should at least print the validation issues. That might be a bit cryptic, but may be better than leaving the user in the dark completely.

Check for database connection when running current_application_settings

The PG connection errors don't always end up being caught as ActiveRecord::NoDatabaseError. So when doing a precompile without the database (like when using the omnibus), an exception was being thrown.

Add placeholder values to hipchat service

This MR adds placeholder values to the hipchat service.
This should prevent issues like #279 or #772 that popped up because people didn't know what exactly they are supposed to enter in the fields.
