Disabled providers are shown in modeler but not in processingtoolbox.
Steps to reproduce:
Disable one or more of external providers(SAGA/GDAL/GRASS GIS) in processing plugin's settings.

ProcessingToolBox tree updates list of providers and algorithms immediately.
But when you open modeler you can see disabled providers (empty treeitem).
Such providers are visible with an empty text and no child algorithms. But this is confusion from user point of view.

ok?
