Remove Introspection from RSpec.current_scope

My reasoning is thus:

rspec-rails need to do the following condition:
`if RSpec.current_scope == :before_all_hook`

test_prof needs to do the following condition:
`if RSpec.current_scope == :before_all_hook`

amd my little helper needs the following
`unless [:before_each_hook, :example].include?(RSpec.current_scope)`
