[BUG] KeepPageCreationModificationInformation will throw error in ConvertTo-PnPPage

[natpdeee]

Problem Area

[x] Page Transformation: Error during the use of page transformation from PnP PowerShell
[ ] Page Transformation: Error during the use of page transformation from .Net
[ ] Page Transformation: Page is not looking correct after transformation
[ ] Modernization Scanner: something went wrong...

Expected or Desired Behavior

Using -KeepPageCreationModificationInformation will carry over the Created, Created By, Modified, and Modified By.

Observed Behavior

Using that flag will always return an error of:
The property or field has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

Steps to Reproduce

Run the following command:
ConvertTo-PnPPage -Identity $page.FieldValues.FileLeafRef -KeepPageCreationModificationInformation -Overwrite -TargetWebUrl $targetUrl -CopyPageMetadata -PublishingPage

Error Log

Message : The property or field has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

PnP.PowerShell version: 1.6.0

I am guessing this issue is similar to this previous issue:
#108

It worked fine previously, but now it always throws an error since around July 2021.
