Zero-rated import not causing battery to discharge beforehand

[chris-y]

Describe the bug
When I have a zero-rated period (power-up) Predbat was discharging as much as possible before the session, so it could charge the battery back up during the session. For some reason this is no longer happening the last couple of times. I'm using 8.16.0 beta but it started before I tried that.

Expected behaviour
Predbat should discharge the battery as much as possible to maximise revenue, and then charge it back up whilst it is free.

8.16.0 beta

Setting metric_min_improvement_export to 3 appears to fix this
