Fix for issue #81

[lgustafson]

This fix for issue #81 will allow the adapters with ssl support (net/http, curb, httpclient) to send client-side certificates even when ssl verify mode is set to none.

@lgustafson You're right. On httpi version 1.1.1, it send client-side certificates like you said. Link here: https://github.com/savonrb/httpi/blob/v1.1.1/lib/httpi/adapter/net_http.rb#L86..L91 You can make some tests about this? The idea is to avoid to happen again.

@rubiii need your help here. What do you think?

[rubiii]

@rogerleite you're right. this looks like a regression and we need more specs for it.

@lgustafson I'm gonna merge the PR on this weekend. Thanks for contribution!
@rubiii I did tests for all adapters unless net/http, that have some TODOs on spec. Ok?

[rubiii]

@rogerleite todo?

[rogerleite]

@rubiii https://github.com/savonrb/httpi/blob/master/spec/httpi/adapter/net_http_spec.rb#L99 this line below, is kind of TODO marking for me. 😄
