ListObjectVersions IsLatest param not working #2481
Description
Hello!
We recently updated past 4.0.0 so our S3Mock has list object version support.
Using PHP's aws-sdk-php making a request to listObjectVersions, which goes to S3Mock.
The params we are using are:
{
"Bucket": "company_name_here-development-bucket",
"Prefix": "685d23e7781af68c590f7512"
}
The results are
{
"RequestCharged": "",
"IsTruncated": false,
"Versions": [
{
"ETag": "\"4a6b392096768046b4be8e833a90a2cd-1\"",

Where as you can see, in the version results, there's one item - it's the only item, but doesn't have the IsLatest key.
Seems like an issue to me - unless I'm missing something, the one result should have the IsLatest as it's the only version.
