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.

Make search for projects case insensitive

### What does this MR do?

This MR makes the search for projects case insensitive.

### Why was this MR needed?
Currently the search for projects is case sensitive.
You can test this on gitlab.com with the search string "perforce" for example.
* perforce returns 2 projects
* Perforce returns 5 projects
* PERFORCE returns 0 projects

This makes it harder to find the projects you are looking for.
With this MR users can find more projects, since they don't need to worry about not seeing some projects just because of an upper letter.

@dblessing Can you take a look at this? :)
