Absolute path in attribute path in paging-directory is taken as relative path

Issue

• When HornetQ journal is specified using absolute paths then it's treated as relative path

<paging-directory path="/NotBackedUp/hornetq/messagingbindings"/>

• The above does creates a directory under 'data/NotBackedUp/hornetq/messagingjournal'

• The same applies for bindings-directory, journal-directory and large-messages-directory
