[ECS] ComponentGroup.SetFilterChanged() does not filter unchanged components or buffers from the group
How to reproduce:
1. Open the attached project ("case_1133331-setfilterchange-bug")
2. Open the repro scene ("SampleScene")
3. Enter Play Mode
4. Inspect the console
Expected results: one "Updating player from history..." can be seen for every "touched history" log
Actual results: the job which has "Updating player history" runs no matter what
Reproducible with: 2018.3.9f1, 2019.1.0b7, 2019.2.0a7
Reproducible Package versions:0.0.12-preview.24, 0.0.12-preview.27
Notes:
1. Couldn't test with 2017.4 because it does not support ECS
2. Couldn't test with earlier ECS versions because of package errors

Resolution Note:
This is expected behavior in the repro case. The repro case calls a system's Update() inside of another systems's Update(), which is going to throw off version number tracking. We've confirmed that if the two updates are called side by side in a SystemGroup, then the changed filter works as intended. We will investigate making this behavior clearer, but the behavior will not change.
