* Correct site extensions build failure
  - mark LoggingBranch project as non-shipping

* Improve site extension versioning
  - ensure `$(SiteExtensionPackageVersion)` doesn't end with a dash
  - remove assumption LoggingBranch and Microsoft.AspNetCore.AzureAppServices.HostingStartup have same version
