Make sync error message smarter on unfound targets

We had two issues here. One is a file with an absolute path passed to -S
results in a cryptic error message due to the database name being '\0'.
The second is not realizing you should be doing -U instead of -S. Fix
both of these to transform this:

    $ sudo pacman -S /tmp/binutils-2.21.1-2-i686.pkg.tar.xz
    error: database not found:

to this:

    $ sudo pacman -S /tmp/binutils-2.21.1-2-i686.pkg.tar.xz
    error: target not found: /tmp/binutils-2.21.1-2-i686.pkg.tar.xz
    warning: '/tmp/binutils-2.21.1-2-i686.pkg.tar.xz' is a file, did you mean -U/--upgrade instead of -S/--sync?
