Delete event, error when Azure object is not present anymore

[mouki9]

In the delete event, whenever the Azure object is not present anymore, this will result in an error in HelloID.
The catch construction is not correctly handled.
On line 75 the $success variable is set to $false, this will result in an error in HelloID.
Also the auditlog part on line 82 - 88 incorrectly sets the auditlog IsError to $true.
