### Current Behavior

When folder names contain a space then `listObjects` returns names without `/` at the end. Without space it works fine.

### Expected Behavior

Folders containing space in the name are returned with `/` at the end.

### How are you starting LocalStack?

With a `docker run` command

### Steps To Reproduce

awslocal s3api put-object --bucket bucket-name --key "folder name/"

awslocal s3api list-objects --bucket bucket-name
```
