basic_get on non existing queue does not throw NotFound, rather times out

[carlhoerberg]

This code:

require 'bunny'
b = Bunny.new("amqp://guest:guest@localhost")
b.start
ch = b.create_channel
puts ch.basic_get "asdfasdfasdfasdfadfs"

Will generate:

/Users/carl/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/bunny-2.7.0/lib/bunny/concurrent/continuation_queue.rb:39:in `block in poll': Timeout::Error (Timeout::Error)

Rather than an expected NotFound error.
