Tweak tributary_test to handle a one-block variance

Browse source 
Prior to the previous commit, whatever async scheduling occurred caused them to
all have the same tip. Now, some are one block ahead of others. This adds
tolerance for that, as it's an acceptable variance, so long as it's solely one
block.
