Title: UP-3591: Instead of returning null preference value, returns specified default value.

This fix should be reviewed in order to verify that "A null value is treated as a non-existent value." (as specified in Portlet API) should be interpreted as proposed pull request is implemented. It is not perfectly clear whether value refers to an array as a whole or individual array entries. These changes assume the latter variant.
