Title: Fails if smtp environment var are not set

Just cloned the repo and ran `rake`, noticed that
`spec/lib/sendgrid_toolkit/common_spec.rb` was raising
SendgridToolkit::NoAPIUserSpecifiedfailing

This fix aims to ensure that the spec passes independently of having
SMTP_USERNAME and SMTP_PASSWORD set.
