Fix incorrect logging of bailout to Open Circuit when using the best gas.
This happened because the starting gas used for 'best gas' calculation
was a diluent - in most cases not a problem as the same gas is also
used as a bailout gas. Now use the 'first' open circuit gas configured as the
starting point.
Also fixes the problem of a custom bailout gas not being logged as such,
and consequently not being shown as bailout in the on-device log.
