"""An AMS label saved before its unit reported a serial (#3348).

A label is kept under the unit's serial, or under the position key
``p<printer>a<unit>`` while the unit reports none. The AMS Lite reported none
until #3348, so its labels sit under the position key, and now the unit comes
with a serial. The label must still show everywhere, be cleared by Clear, and
move to the serial when it is saved again.
