Closed Issue: Update-package Foo no longer works to update all projects [3043]

Trying to update all packages in a solution no longer functions. However using a specific -project target it succeeds. It also succeeds if I specifically use install and a project.

Update all
```
C:\Projects\FooPM> update-package System.ExtensionMethod
update-package : 'System.ExtensionMethod' was not installed in any project. Update failed.

Update -project
```
C:\Projects\FooPM> update-package System.ExtensionMethod -project Services
