Title: utils_vl_lookup: Fixed a race when creating user objects.

This could cause multiple aggregation instances to be created in the
aggregation plugin when first writing data to the plugin. This, in turn, led
to "value too old" warnings because subsequently all data was submitted twice.

Thanks to @faxm0dem for reporting this in GH #535.
