Update ec2-automate-backup-awscli.sh

Tagging fails due to error "aws_ec2_create_tag_result='A client error (InvalidID) occurred when calling the CreateTags operation: The ID '\''2014-10-21T13:34:24.000Z'\'' is not valid'"

The command "aws ec2 create-snapshot --region $region --description $ec2_snapshot_description --volume-id $ebs_selected --output text" is giving less information, so the position of the ID has changed.
