[rubygems/rubygems] Skip duplicated dependency warning for gemspec dev deps

Generally this warning is skipped for gemspec development dependencies.
I think because it's common to override them in the Gemfile to change
the source, for example.

But the order of conditions was not correct and the warning was still
being printed in one case.
