Fix WebHookService spec failing in Ruby 2.6
Ruby 2.6 changed Net::ReadTimeout#message
to include the reason for the
socket error (https://bugs.ruby-lang.org/issues/14832). However,
WebHookService
was failing in Ruby 2.6 because it expected
Exception#message
to match Exception#to_s
, which isn't always the
case. Fix this by just checking Exception#to_s
.
