Current build seems to be failing

Looks like it's not a huge deal: https://github.com/polds/logrus-papertrail-hook/blob/master/papertrail_test.go#L56 its expecting a papertrail host/port combination to be set in the environment which the build does not have.

I'll look into porting it to a self hosted TCP server for the tests.

Made fake tcp request via conn interface #5
I think it will be enough. In hook module we shoud test only if fire function works as expected.
Testing full tcp/upd connect with sending data is superfluously. There are tests in dial package.

@undiabler that looks good to me, thank you. Merged.
