    libtracker-common: Make libicu/libunistring agree on function prerequisites
    
    We can possibly end up with tracker_parser_unaccent_nfkd_string() called on
    0-length strings. Libunistring already handles/accepts this fine, the libicu
    implementation already is 0-length safe, so have it accept 0-length strings
    as well.
