Don't overwrite certain values if the refreshing comes in via short updates

This e.g. happens from the talk participant list which only has the status, message and icon.
Due to the overwriting e.g. the clearAt was overwritten with null
and afterwards the status modal showed "Invalid date" as "Clear at"
