- The problem here is that due to the nature of the relationship and the
way the loop was set up it was possible to miss some relationships:
A _ C
\_ D
B _ E
\_ F
Since we looped over A and B and did a break when we found something to
attach it to (in this example A would find C) it would break. What we
should be looping through is CDEF and finding a home for each one.
Did the same change in to_one though it doesn't matter since it's
one-to-one.
to-many is untouched because it's already looping over CDEF and finding
a home for it because the relationship is reversed.
