Title: gh-2161 Only 1 package can be active per queryset / packagemap

Package add needs to make sure that there is only 1 active package
at a time for a queryset. Roxie will only process the first active
package, so when adding a package (or activating an exisiting package)
the code needs to deactivate the currently active package first
