ID 405652 - When a node has lifetimeStart enabled and the start or end value is set to 0 the value is not saved.

Problem summary
When a node has lifetimeStart enabled and the start or end value is set to 0 the value is not saved.

Nuke doesn't set this value within the node's script as it is the nodes default value, due to this when the node is copied and pasted it will use the start and end time set within the viewer.

Customer reported version

Customer reported platform

Steps to reproduce

1) Open Nuke and create a Grade node.

3) Enable use lifetime and set the lifetime range to 0 and 0. ) Enable use lifetime and set the lifetime range to 0 and 10.

4) Copy and paste the Grade1 node, this will create a Grade2 node.

5) Notice that the lifetime range of the Grade2 node is set to the viewers time range.

Expected behaviour
The Grade2 nodes lifetime range should be set at 0 and 0.

Actual behaviour
The Grade2 nodes lifetime range is set to 1 and 100.
