    ofono: Skip whitespace between vCards when splitting them up
    
    This eliminates the following libebook warning which we were triggering.
    libebook itself skips the whitespace, so this introduces no functional
    changes.
    
        libebook-contacts-WARNING **: vcard began without a BEGIN:VCARD
