Now QGIS always reads all features of a layer to calculate the extent when the layer is opened.
It is very slow for big layers.

See:
#500116bfe337760a21a6c34ac16073eba5fefe40#diff-106be592650b55ccae79c83eecd15cebR1691

Re-enabling this code, the layer fetch the extent from provider:

QgsRectangle mbr = mDataProvider->extent();
setExtent( mbr );
