Set the default target exposure to the minimum value, not 0 (#13562) 
# Objective

- In particularly dark scenes, auto-exposure would lead to an unexpected
darkening of the view.
- Fixes #13446.

## Solution

The average luminance should default to something else than 0.0 instead,
when there are no samples. We set it to `settings.min_log_lum`.

## Testing

I was able to reproduce the problem on the `auto_exposure` example by
setting the point light intensity to 2000 and looking into the
right-hand corner. There was a sudden darkening.

Now, the discontinuity is gone.
