Confusing trash icon in action-mode menu when adding members to group

[adbenitez]

when using the "add member" option in a group, the contact list is displayed to select/deselect members, this is the same contact list that is shown when pressing the (+) button in the chatlist, if you long-press a contact there, you get a trash-icon option to remove the contacts from the contact list, this however is confusing when seen in the context of group member list and people can use it expecting it would mean "remove member from group", the option is better removed from there
