SourceControl: Error: Operation 'UpdateChangelistsStatus' not supported by source control provider 'Subversion'

When trying to check in a new asset or changed asset via the source control menu or Tools menu, an error comes up in output log.

SourceControl: Error: Operation 'UpdateChangelistsStatus' not supported by source control provider 'Subversion'

You can check in the asset if you right click it and select Source Control>Check in

However, if you delete the asset, there is no way to check in the deletion as you do not have an asset to right click on and bring up the check in changelist window.

Regression:  This same test has been done and passed on //UE4/Release-4.26.2 on several CL.  

New Regression testing was done in //UE4/Release-4.27.2 CL-18427296 and this issue DID NOT happen.
