[QGIS-Developer] Refactor fields processing algorithm

[Andreas Neumann]

Hi,

This is about QGIS master.

The refactor fields processing algorithm, when opened manually in the 
toolbox, has an option to run the algorithm only on selected features.

However, when the same algorithm is included in a model, this option 
"only selected features" is not available anymore.

Is there a workaround? How would I run this algorithm in the model only 
with the selected features? In QGIS 2x there was a processing option to 
always run processing with selected features only - but this option is 
now gone in QGIS master.

Thanks for your help,

Andreas
