Look in target-list first to resolve dependencies
This fixes a bug introduced by my previous changes which changes the behavior of IgnorePkg/IgnoreGroup to allow the user to remove unresolvable packages from the transaction. The bug is that the target-list was no longer being consulted first to resolve dependencies, which means that if two packages in the sync database satisfied a dependency, and the user explicitly requested one of those two packages in the sync, the other package was still being pulled in. A new test was added, sync993.py, to verify the desired behavior. Signed-off-by: Bryan Ischo <bji-keyword-pacman.3644cb@www.ischo.com> Signed-off-by: Dan McGee <dan@archlinux.org>
