Remove deprecated setting, rspec3 forces this true.

RSpec::Core::Configuration#treat_symbols_as_metadata_keys_with_true_values= is deprecated. Called from /Users/sane/work/ruby-study/tachikoma/spec/spec_helper.rb:8:in `block in <top (required)>'.

Deprecate config.treat_symbols_as_metadata_keys_with_true_values = false. RSpec 3 will not support having this option set to false. (Myron Marston)
