Qt: Actually ensure that rows are colorized

PacketListRecords should only report themselves as colorized when
colorized with the latest version of the coloring rules. Otherwise,
ensureRowColorized will not recolorize rows when the rules have changed.

This makes the minimap/intelligent scrollbar correctly update
colors in the background when the rules have changed. (Rows that
were being displayed were being updated, because the columnStrings
were invalidated at the same time, and when fetching the columnStrings
the colors would be updated if the rules had changed.)
