[tracker] tracker-tag: Fix coverity report

[Carlos Garnacho <carlosg src gnome org>]

commit 5e8923e19a5429554bc6da4761d2874778a2f8bc

    tracker-tag: Fix coverity report
    
    urns was possibly uninitialized when used. Also, removed the uris
    variable declaration inside the if (uris && *uris) block, since
    it was obviously redeclared and reused for exactly the same purpose.
