Chef::Provider::Package::Homebrew#current_installed_version

Some packages (formula) are "keg only" and aren't linked,
because multiple versions installed can cause conflicts. We
handle this by using the last installed version as the
"current" (as in latest). Otherwise, we will use the version
that brew thinks is linked as the current version.
