fix group picture msg - now from group, not sender

Denver Gingerich created 

Prior to this commit, picture messages sent to a group would appear to
come from just the sender, without any mention of the group (i.e. as
if the sender had sent the picture only to the SGX user).  With this
change, picture messages are correctly shown as being from the group,
utilizing the address list creation added in 90331bc.  Note that a
deep clone of the template message is required (via .copy) to ensure
that send_media() doesn't modify the original, which often contains
text that we need to send separately (done later in the code).
