Update override config to include some changes from global config

Browse Source 
In override config for task we set Configuration#screenLayout field based on
initial global config + shrink to fit the area on screen given for this task.
However this field also contains information (like layout direction) that we
do not intend to override and it can be changed in global config separately.
In this case we need to update the override config with changes from global
config.
