Title: add support of layerGroup's isExpanded parameter

Default layertree behaviour is to expand then collapse the treenodes. For layergroup of first level (directly linked to a theme), this change reopens them.
Note that it doesn't work for layergroups themselves embedded in a parent layergroup (TODO).
