ObjectListView, Phoenix and Py3

Hi,

I run into different 'unorderable' errors with OLV, depending on column content, and Py3, e.g.:

builtins.TypeError: unorderable types: NoneType() < datetime.datetime()

When sorting a column containing dates but also None values.

The problem is with OLV._getSortValue, I managed to fix above error but then get it on other columns.

Anyone updated this already for Py3?
