dnf method alone doesn't show package output

[PriamX]

In the master branch, line 1571:

pac "$(sqlite3 /var/cache/dnf/packages.db "SELECT count(pkg) FROM installed")"

...does not increment the packages variable, thus if dnf is the only package method packages will equal zero and the "Packages:" line is not displayed. Here's my very humble and mostly untested fix:

# Using the dnf package cache is much faster than rpm.
if has dnf && type -p sqlite3 >/dev/null && [[ -f /var/cache/dnf/packages.db ]]; then
     dnfcnt="$(sqlite3 /var/cache/dnf/packages.db "SELECT count(pkg) FROM installed")"
     pac "${dnfcnt}"
     packages+=${dnfcnt}
else

I don't think this is true. Since has {manager} sets the manager variable and pac {count} appends the count with the manager to the finalized package count string, the original implementation should be correct. And it also runs correctly on my Fedora vps so it's correct.
