issue if using reqwest v0.12.0 and above

[SniffleSneeze]

Hi everyone,
I've recently started to use that great library after watching on of your video @jeremychone and I love it. However in my case some of my testing required me to set the header for auth therefor I've use the reqwest_builder i.e. reqwest::ClientBuilder to be use in conjonction with the httpc_test::new_client_with_reqwest. So far so good, however the issue I want to raise is that for what ever reason if you use a version of reqwest v12 and above you receive that annoying:

expected ClientBuilder, found a different ClientBuilder

I fafed around with different version and everything work fine until you chose v0.12.0 Max supported is v0.11.27.

Thanks for your great work and I hope I'm writting this in the right place.

Alex
