    magic-decompressor: Fix handling of uncompressed info pages
    
    When an uncompressed info page is specified, function
    yelp_magic_decompressor_convert always returns G_CONVERTER_CONVERTED.
    This causes file loading to never be completed because function
    g_input_stream_read keeps waiting for new data until the converter
    returns G_CONVERTER_FINISHED.
