Fix insurance deviation not firing with soft hands (#124)

The _suggest method returned early for soft hands, which is correct
for play deviations (no I18 entries for soft totals) but wrong for
insurance, which is independent of the player's hand. A player with
A+2 (soft 13) at TC >= 3 was told not to buy insurance.

Fix: skip the soft-hand check when the step is WaitingForInsuranceInput.
Bump version to 0.35.12.
