This test is useful because before the last commit using copy_image
would not set the owner_id to the same one used when calling
describe_images.
For example, this code
conn = boto3.client("ec2")
copy_resp = conn.copy_image(
SourceImageId="ami-whatever",
...
)
describe_resp = conn.describe_images(
Owners=["self"]
)
Would result in describe_resp being empty, when it should contain the
image from the copy_resp before it.
By ensuring the owner ids are the same (see ce4059f6) the code example
now works as expected.
