Powershell shouldn't install modules to MyDocuments as thats not for applications

Microsoft is pushing more and more during Onedrive setup to have MyDocuments managed by onedrive.

Being a good dev and not running elevated means installing packages with -Scope CurrentUser but this means packages are stored in MyDocuments\WindowsPowershell or MyDocuments\Powershell. This means all modules are then synchronised up to OneDrive.

This is made worse by sporadic issues due to connecting of Onedrive.

1. Collisions with OneDrive and the install-module resulting in modules not saving correctly
2. Modules not used in a while get "archived off" and thus are downloaded on demand by onedrive resulting in problems when trying to load modules

Use of AppData would be much more appropriate for modules.
