Minor fixes for Baloo

[Vishesh Handa]

I was notified of another crash by the Kubuntu team. I'll also be pushing this 
patch unless there are objections.

    FileIndexingQueue: Catch exception
    
    This can happen in the case when the extractor fails to index a file and
    at the same time managed to remove the indexed data from the xapian db.
    So weird.
