Fix method primitive return type

[MIchaelMainer]

Methods that return primitives returned JSON objects and not just the OData primitive values. An update needs to occur in the generator and core to support this scenario.

Depends on microsoftgraph/msgraph-sdk-dotnet-core#135. Tests won't pass until this is published.

Generated with microsoftgraph/MSGraph-SDK-Code-Generator#300

The following methods will now be supported:
