This circumvents the no-nesting rule of the new `travel_to` in Rails TimeHelpers

better_travel_to.rb

# The new `travel_to` does not allow nested calls, and instead throws the following error
# in your face whenever you try to use it:
#
#   Calling `travel_to` with a block, when we have previously already made a call to `travel_to`, can lead to confusing time stubbing.
#
# Using this module to override `travel_to` will solve that issue.
#
# Note: not guaranteed to work perfectly
#
module BetterTravelTo
  # The original `travel_to` does not allow nesting
