Make QgsVectorLayerExporter::flushBuffer public

Sometimes it's necessary to manually call this, instead of deleting the exporter and letting it be called automatically There's a chance that features in the buffer will cause errors while being exported, and if the only way to flush the buffer is to delete the exporter then there's no way to detect or retrieve these errors.
