Edge case: creating new Object on 2 different devices with the same key

[pgmemk]

Flow:

• Create objects with the same key on different devices: Device A and Device B
• The Device B is receiving the Diff from the Device A after Device B submitted the same key object.

As a result:

• Device B has the newly created object and the Diff from the Device A for the same object
• Timestamp of this Diff from the Device A is earlier than created by Device B Object

To solve this we chose the following approach

• check the Diff from Device A and see if the Diff was for creating a new Object. This Diff will not have _prevTimestamp property set.

If YES

• create new Object from the Diff from Device A
• save it in Store to preserve the same state for all devices
• generate Diff object between the newly created Object and the one that was originally created on Device B
• merge the genned Diff with the newly created Object
• save merged Object in Store

If NO

• This is still in discussion 😀
