Bugfix: arsn 116 fix listing master returning phd

[Kerkesni]

When the last version of an object is deleted a placeholder master key is created and is kept for 15 seconds before it gets repaired.

To avoid listing the PHD keys we added a transform stream that replaces PHD master keys with the last version of that object

For ease of readability, the internal listing function was divided into two functions one for each bucket version format
