Implementation of prefix mapping specific to databases.
This extends the base implementation, effectively turning it into
a write-through cache - each new namespace is written to
the database as it is added to the prefix map.

Constructor for a persistent prefix mapping.
Each GraphRDB has a set of associated properties
which are, themselves, represented as triples in
a system graph.
The prefix mapping is persisted by converting it
to triples and storing it along with the other
properties of the GraphRDB in that system graph.
Parameters: graphProperties - the system properties of a persistent graph.
