[tracker/wip/carlosg/coverity-fixes: 4/16] tracker: Test return value of g_file_get_contents()

[Carlos Garnacho <carlosg src gnome org>]

    tracker: Test return value of g_file_get_contents()
    
    Check for the return value of this function, since coverity seems
    to like it checked (and does not understand the error is only filled
    in case of error).
