CLDSRV-498 Handling isNull master version with no versionId

[nicolas2bert]

In certain cases, a master version may not have a versionId and be set as null (isNull:true). For instance, this occurs when a customer:

• Create a bucket.
• Put an object to it.
• Put bucket versioning.
• Put metadata (BackbeatClient.putMetadata), which results in the master version being set to null (isNull:true) with no versionId.

Currently, if an object is put after these steps, CloudServer fails to appropriately generate a null version. This is because CloudServer doesn't handle situations where the master version is set to isNull:true with no versionId.

The correct approach when an object is put should be to:

• Create the new version key.
• Create a new null version key, assigning it a “default non-version version id”.
• Update this “default non-version version id” to the nullVersionId field of the master key.
