Packer does not copy AMI tags cross accounts

#### Overview of the Issue

I am building an AMI and copying it to another 3 regions and to another 3 accounts. The tags in the AMI are copied successfully along with the AMI to the another regions, but not the another accounts.

#### Reproduction Steps

Creates a new AMI with the following snippet
```
data "amazon-ami" "amazon_linux_2" {
access_key = "${var.aws_access_key}"
filters = {
name = "amzn2-ami-hvm-*-x86_64-gp2*"
root-device-type = "ebs"
virtualization-type = "hvm"
}
}
```

Add the tags block:
```
tags = {
Name = "amazon-linux-${regex_replace(timestamp(), "[- TZ:]", "")}"
ansible = "true"
packer = "true"
cross-account = "true"
}
```

Copy the AMI to another regions, example:
`ami_regions = ["us-east-1", "us-east-2", "us-west-2"]`

Copy the AMI to another accounts, example:
`ami_users = ["account_id_1", "account_id_2", "account_id_3"]`

The AMI is created in the accounts `account_id_1` in `us-east-1`, `us-east-2`, `us-west-2` with the proper tags. The AMI is copied to `account_id_2` and account_id_3 successfully, but the tags are not there.
