Fix provider menu showing when it shouldn't

If the package is already installed, we need to check if it is in the
repos to see if it aplies to rebuild tree. Normally alpm will not prompt
us to select a provider if we already have one installed. An exception
comes up when we have a provider installed that is from the AUR. In this
case FindSatisfier() still asks us to select a provider.

Now make sure to never to never show the menu if the package exists in
the local repo.
