[Android] unscaledDeltaTime and deltaTime return abnormal / negative values
Steps to reproduce:
1. Open attached project "TimeDeltaTime2.zip"
2. Run on older Android OS (4.*~)
3. Lock screen while app is running
4. Leave it for a little while (15-30 minutes)
5. The delta time values will return negative values sometimes
Expected: delta time values return normal numbers, never negative
Actual: Sometimes the time is negative, which doesn't make sense. (The min: value on screen shows the minimum value of deltaTime recorded)
2018.1.0b8, 2017.3.1p1, 2017.2.1p4, 2017.2.0f1, 2017.2.0b1, 2017.2.0a3, 2017.2.0a2
On 2017.2.0a1 the project lags, akin to a repro, but the values are not displayed as negative, so not sure about this one.
No repro: 2017.1.3p1
