Fix delivery/twilio Ruby 3 Compatibility Issue

[Ancez]

Fixes an issue caused by passing down a hash to a method which expects kwargs

Failure/Error: texter.deliver_now
     
     ArgumentError:
       wrong number of arguments (given 1, expected 0)
     # /lib/twilio-ruby/rest/api/v2010/account/message.rb:130:in `create'
     # lib/textris/delivery/twilio.rb:20:in `deliver'

Specs are not passing caused by render_anywhere compatibility issue with Rails 6, more on this here: #55 and #50
