MODE-2395 - Added Arquillian integration test to reporduce the issue described in MODE-2395

Added Arquillian test to recreate the issue described in MODE-2395. When running the test please ensure that standalone-modeshape.xml has the following Infinispan cache configuration:

<local-cache name="sample">
    <locking isolation="READ_COMMITTED" striping="false"/>
    <transaction mode="NON_XA" locking="PESSIMISTIC"/>
    <file-store passivation="false" purge="false" path="modeshape/store/sample"/>
</local-cache>
Is a *new* session injected on each method call, or are the sessions reused from call to call?
