Fixed problems when the --dnaHeaderOnly flag is true

    A KeyError was occurring when the --rnaOnly flag in filterRadia.py
    was set to true resulting in the --dnaHeaderOnly flag here to
    be set to true.  When merging the rna and dna filters, we need
    to check if only the dna header is loaded from the dnaFile.
    In addition, the non-overlapping RNA calls that don’t pass the
    germline and pseudogene filters were being omitted from the
    final output. They are now added with the 'dnacall' filter
    to show that they are non-passing.
