It's just a nice, lesser known convenience function. Exists since
PHP 5.5.
The changes to SerializationTestTrait ended being a little different.
Original I tried to use array_column() as well. But it drops the
array keys, which is relevant here.
We found that calling the two methods getTestInstances(AndAssertions)
multiple times is quite expensive and should be avoided. I changed
the code slightly so it's much less likely this is done unintentionally.
