Error when deleting credentials

Describe the bug An error is generated, using version 1.9.1, for missing variable $adfi when trying to remove a credential that is no longer in config files.

It appears on line 16 $adfi should be $adfInstance which then generates the error inside of Remove-AdfObject.ps
