[BUG] false error reported from Add-PnPFolder on large Library

[petecalvert]

When calling Add-PnPFolder on a large library it returns:
Add-PnPFolder : The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator.
But still creates the folder.

Notice

Many bugs reported are actually related to the PnP Core Library which is used behind the scenes. Consider carefully where to report an issue:

1. Are you using Apply-PnPProvisioningTemplate or Get-PnPProvisioningTemplate? The issue is most likely related to the Provisioning Engine. The Provisioning engine is not located in the PowerShell repo. Please report the issue here: https://github.com/pnp/PnP-Sites-Core/issues.
2. Is the issue related to the cmdlet itself, its parameters, the syntax, or do you suspect it is the code of the cmdlet that is causing the issue? Then please continue reporting the issue in this repo.
3. If you think that the functionality might be related to the underlying libraries that the cmdlet is calling (We realize that might be difficult to determine), please first double check the code of the cmdlet, which can be found here: https://github.com/pnp/PnP-PowerShell/tree/master/Commands. If related to the cmdlet, continue reporting the issue here, otherwise report the issue at https://github.com/pnp/PnP-Sites-Core/issues
