Systems with sub emitters set to inherit "everything" now will also inherit lifetime.
This is an issue particularly with death sub emitters which spawn when their parent's life is at 0, which effectively means no on-death sub emitters will trigger.

Repro steps.
1. Open Scene1 from the attached project in 2017.1.0f3 or earlier.
2. Press play and observe the result (gif attached).
3. Open the project in 2017.2.0b3 or later.
4. Observe how the death sub emitter is not playing.

Notes:
- Regression, introduced with the addition of "inherit lifetime" for sub emitters.
