Description

When running a series of in session and sessionless request from the same client, an in session transaction can be opened by a sessionless request.

This failing test (in GremlinServerIntegrateTest.java) demonstrated this:
https://github.com/PommeVerte/incubator-tinkerpop/commit/f8d4e618a74821f72dc1e3c107cd3b30d34917f2

If these same requests are made from two different clients there are no issues (see test in GremlinDriverIntegrateTest.java)

Rundown of what the tests do :

• Open a transaction (in session)
• Add vertex (in session)
• Commit transaction (in session)
• Test if transaction is closed (in session) =TRUE
• Send sessionless read request.
• Test if transaction is closed(in session) =FALSE <--- bug should be =TRUE

The bug only occurs if there's a sessionless read, and if the read returns elements (not FastNoSuchElement...).
