in the past, group-messages were marked as "read by recipient" only when at least 50% of the group members have send a read receipt - in practise, this does happen never or much too late esp. in larger groups. setting the state OutMdnRcvd already on the first read-receipt seems to be much more intuitive and useful as you at least know one person has read the message. this is also what other messengers as telegram are doing here. moreover, this fixes a bug that did not add all read-receipts to the "Info" screen - once "enough" read-receipts were received, and the state was already set to OutMdnRcvd, subsequent read-receipts were ignored. probably because the "Info" screen did not show the read-receipts since forever - and for the second tick, the addutional read-receipts are not needed.
