SharingSettings is null in every new instances of ProvisioningTenant

Hi,

I just bumped into this when trying to implement a Handler-filter kind of rule, in which I look into the strongly-typed ProvisioningTemplate object for each Handler related property, and decide whether or not the associated Handler should be passed to ApplyProvisioningTemplate(ProvisioningTemplate, ProvisioningTemplateApplyingInformation).

ie. for Files or ContentTypes, I safely check if the collection contains any element. For Header or Footer, I check if they are null, etc. But for some properties (the ones implementing IEquatable<>) I rely on the fact that they are equals (or not) to their default instance equivalent.

Basically, is it true that myTemplate.Tenant.Equals(new ProvisioningTenant()) ?
It works like a charm for every properties in the template but the Tenant one, because in a new instance of the ProvisioningTenant class, the SharingSettings property is not initialized (unlike others), and then calls to .GetHashCode() or .Equals() just throw a NullReferenceException.

Would it be a good choice to initialize a new SharingSettings() in the property getter ? If yes may I send a pull request to this repository ?

Many thanks !

Start with the ProvisioningTenant and SharingSettings implementations, focusing on the SharingSettings property and the Equals/GetHashCode paths mentioned in the report. Reproduce comparisons against a new ProvisioningTenant and verify that those operations no longer throw a NullReferenceException when the property has not been explicitly set.
