This method figures out which matcher should be the inner matcher and which

For example, we need it to be this:
up the call stack, we need to order things so that it is the inner matcher.
For a matcher like `raise_error` or `throw_symbol`, where the block will jump

  return @matcher_1, @matcher_2 unless self.class.matcher_expects_call_stack_jump?(@matcher_2)
  return @matcher_2, @matcher_1 unless self.class.matcher_expects_call_stack_jump?(@matcher_1)
  raise ArgumentError, "(#{@matcher_1.description}) and " \
    "(#{@matcher_2.description}) cannot be combined in a compound expectation " \
    "because they both expect a call stack jump."
