Handle SSH keys that have multiple spaces between each marker

See merge request !10466

[ci skip]

Notice what happens when a user adds a key with a space in between:

```
irb(main):004:0> 'ssh-rsa  foobar'.split(/ /)
=> ["ssh-rsa", "", "foobar"]
```

This would cause gitlab-shell to receive a blank argument for the actual
key, leading to users unable to login.

This param is passed to service in two places, one is in the build_user for non ldap oauth users. And the other is in the initial production admin user seed data.

Without this change, when setting up GitLab in a production environment, you were not being given the option of setting the root password on initial setup in the UI.

This is a proof of concept for gitlab-org/gitlab-ce#30196.

The actual login procedure is well-tested by
`spec/features/login_spec.rb`, and we don't gain anything by also
thoroughly testing it here, in our second-slowest feature spec. In fact,
it only slows us down!

So instead we use `sign_in` from the `Devise::Test::IntegrationHelpers`
module, which just sets the current user at the Warden level. This
drastically reduces the "setup" phase of every test in this file. A
non-scientific test run saw this drop from 633 to 231 seconds.
