InfinispanBinaryStore does not clean up temporary files

It looks like the temporary file (used for hashing to get an identifier) is not cleaned up in the InfinispanBinaryStore:

https://github.com/ModeShape/modeshape/blob/master/modeshape-jcr/src/main/java/org/modeshape/jcr/value/binary/infinispan/InfinispanBinaryStore.java#L192

(Or, if it is cleaned up, it isn't until the process terminates, which is undesirable too)
