Don't crash when cleaning the uninitialized fontdatabase (Symbian)
Applications that do not render fonts will not cause a call to
initializeDb(). In that case, there will be no creation of
QSymbianFontDatabaseExtras.
This fix adds a NULL-pointer check before cleaning the
QSymbianFontDatabaseExtras instance.
Task-number: QTBUG-11683
