Fixes #2900
The last segment is not allowed to be empty. Also adds tests for UID construction.
Originally I thought (and still think) that empty segments make no sense at any position. But at least for
ThingUID
there is a test that ensures that a missing thing-type is considered a valid UID.Signed-off-by: Jan N. Klug github@klug.nrw
