/* This test is a bit interesting. It tests a case where we've got a property that sits in one
* property block and the value is of a long type. So given that plus that there's an index for that
* label/property, do an update that changes the long value into a value that requires two property blocks.
* This is interesting because the transaction logic compares before/after views per property record and
* not per node as a whole.
*
* In this case this change will be converted into one "add" and one "remove" property updates instead of
* a single "change" property update. At the very basic level it's nice to test for this corner-case so
* that the externally observed behavior is correct, even if this test doesn't assert anything about
* the underlying add/remove vs. change internal details.
