ProjectPrivate: found the nasty bug that caused a wrong item being shown in the plugins using GenericOCIO! That was a nasty one, @MrKepzie
what happened is that the ChoiceParam was after the sStringParam
When the StringParam was loaded, the ChoiceParam was correctly set…
but later on, the ChoiceParam was also deserialized, but it contained the default value (0), since it was non-persistent!!!
