Missing S3FileSystemInfoTest.java

[stefanofornari]

Hello, I noticed that the test class in the subject is not anymore there. Is it wanted?

Hmm, it may have gone missing during the refactoring. Will need to pull it back in from a prior commit.

Just checked back through the last five releases and I'm not sure we ever had a test for this. Unless I am looking in the wrong place. I can see one for S3XFileSystemInfoTest.java
