Merge commit from fork

* Bumped version to 10.8.9.

* Fixed parsing of node if in content and media permission querystring handlers to retrieve expected value when multiple are provided in the querystring.

# Conflicts:
#	tests/Umbraco.Tests.UnitTests/Umbraco.Web.BackOffice/Authorization/ContentPermissionsQueryStringHandlerTests.cs
#	tests/Umbraco.Tests.UnitTests/Umbraco.Web.BackOffice/Authorization/MediaPermissionsQueryStringHandlerTests.cs

* Add HttpPost attributes to backoffice endpoints that should only accept post requests.

* Narrow PermissionQueryString parsing to the releveant UmbracoObjectType

* Add missed update from v10
