BackendStatusTask fails if Guide status fields comment and next is not present or empty

[espenaf]

Using trunk with mythtv-service-api-0.0.32

A freshly installed MythTV 0.26 box with only a FREEBOX encoder gives me the following Guide status on the status page;

  <Guide status="Successful." next="" end="Wed Sep 4 2013, 10:52 AM" start="Wed Sep 4 2013, 10:52 AM"/>

As there is no guideThru, comment, guideDays fields, and no next value, the following stack trace is thrown for the comment part, similar for next.

Settings the required = false to the fields does stop the error, but might fail other things i guess.

Looks good on 0.26.
