Exchange online and MGGraph are interfering

Harm_Veenstra 

Thank you Harm, I noticed this version, and my quick testing shows improvement:
* Connect-ExchangeOnline works with interactive login, managed identity, and a certificate (App Registration).
* With all login methods above, I can also do AzConnect and MgConnect with a Managed Identity or a certificate (App Registration).
* Sadly, connecting to IPPSSession is only possible with a Personal Account (interactively). Managed Identity was never supported to Purview (and probably never will be), and App Registration with certificate now produces a very unspecific error:
---
An error has occurred.

+ throw $_.Exception;
+ ~~~~~~~~~~~~~~~~~~
+ CategoryInfo : OperationStopped: (:) [], SystemException
+ FullyQualifiedErrorId : An error has occurred.

Just trying to connect to IPPSSession will load some assemblies, which will cause Connect-MgGraph to throw the following error: Connect-MgGraph: Invalid JWT access token.
This won't happen when connecting to IPPSSession with a Personal Account (interactively).

Sadly, I need to connect to Purview with App Registration while simultaneously connecting to Azure and MgGraph. This is a pretty wild combination, but the client project requires it.

After all, I will have to stick with 3.4.0, but thanks for the update.
