There was previously a bug in resolve where turning off the default set of features would cause resolve to not correctly settle on the set of features activated for a package. If one dependency turned off all features, and then the next dependency to be activated only turned on the default feature, the default feature wouldn't actually end up getting activated. This commit alters the check to see if the package has been previously activated to more rigorously check to see if the 'default' feature is activated previously. If a dependency doesn't use the default feature, or if the package itself does not have the feature "default", then the package is considered activated, but otherwise it needs to go through another cycle of resolution.
