Subject: [PATCH] PB-1211 : do not add ; if layer with feature selection is
 alone

When opening the app with a layerId=featureId URL param, the ; was still added to the layers URL param after processing the feature pre-selection. This means the layers URL param was malformed and an error showed up.
