Running QA against staging fails

I'm creating this issue to investigate/troubleshoot what's going on.

Today I've tried running QA against https://staging.gitlab.com and I stumbled upon the following issues:

  • Running GITLAB_USERNAME=gitlab-qa GITLAB_PASSWORD="REDACTED" gitlab-qa Test::Instance::Any EE latest https://staging.gitlab.com failed with

/Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/docker/specs.rb:34:in +': no implicit conversion of Fixnum into String (TypeError) from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/docker/specs.rb:34:in block in test_address' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/docker/engine.rb:17:in block in run' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/docker/engine.rb:16:in tap' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/docker/engine.rb:16:in run' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/docker/specs.rb:26:in test_address' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/scenario/test/instance/any.rb:13:in block in perform' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/scenario/actable.rb:15:in perform' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/scenario/test/instance/any.rb:12:in perform' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/scenario/template.rb:8:in block in perform' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/scenario/template.rb:6:in tap' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/lib/gitlab/qa/scenario/template.rb:6:in perform' from /Users/remy/.gem/ruby/2.3.5/gems/gitlab-qa-0.2.2/exe/gitlab-qa:7:in <top (required)>' from /Users/remy/.gem/ruby/2.3.5/bin/gitlab-qa:23:in load' from /Users/remy/.gem/ruby/2.3.5/bin/gitlab-qa:23:in `'

which is solved in `master` but we didn't release a new version of the gem yet.
- Running `GITLAB_USERNAME=gitlab-qa GITLAB_PASSWORD="REDACTED" bin/qa Test::Instance::Any EE latest https://staging.gitlab.com` (in the `gitlab-qa@master` project) failed with the following errors:

I think the problem is that we're visiting `visit('/')` in https://gitlab.com/gitlab-org/gitlab-ce/blob/b16c2ef7d5c4e7696b51c7e410381b316be128a6/qa/qa/page/main/entry.rb#L6 but on https://staging.gitlab.com this redirect to https://about.gitlab.com/. I think if we change that to:

```diff
diff --git a/qa/qa/page/main/entry.rb b/qa/qa/page/main/entry.rb
index a9810beeb2..91c1aef70a 100644

   module Main
     class Entry < Page::Base

+          visit('/users/sign_in')

         # This resolves cold boot / background tasks problems
         #

That would probably solve the problem.
