fix handling of zero importance

To avoid importance becoming zero and cancelling out other weights,
df008d99f549d850d07580b4592435388e44387c introduced a minimum value
for importance. That broke importances for interpolated addresses,
which are less than zero.

Instead of setting a minimum, set zero importances to a very small
value.

Fixes #2753.
