when the style changes tb.zoomLayers must be reset

[jscastro76]

the zoomLayers must be reset, otherwise there will be an error raised on zoom. this could be made on styledataloading or in style.load, to investigate

map.on('styledataloading', function() {
console.log('A styledataloading event occurred.');
});

[jscastro76]

Finally made in the new call to style.load

this.map.on('style.load', function () {
			this.tb.zoomLayers = [];
