It looks like it should be possible to use just a LIST call here because we
don't need the full metadata from the HEAD request. Metadata is only used for
the existence check and for the file size, which should be available from the
list response:
```java
// list object to force strong consistency
ListObjectsV2Response response =
client().listObjectsV2(ListObjectsV2Request.builder()
.bucket(uri().bucket())
.prefix(uri().key())
.build());
Preconditions.checkState(response.contents().size() <= 1, "Invalid
file: %s contains more than one object", uri);
this.exists = response.contents().size() > 0;
this.length = response.contents().get(0).size();
```
