BUG/MINOR: deviceatlas: refresh the user-agent evidence id after a reload

The user-agent evidence id used by da-csv-conv was only computed at init.
Ids belong to the data file, so after a hot-reload of a file with a
different header list, da-csv-conv could pass a stale id and return wrong
or empty properties until restart.

This should be backported to lower branches.
