fix(trimScale): check for zero value in countTrailingZeros

[reckter]

trimSccale, when called with a 0 as the amount, kept in a endless loop.

Cause:
countTrailingZeros was stuck, as there never was any non-zero value to brake the loop.

I am unsure wether this is the cleanest solution, but it at least fixes the problem.

Also added a quick test for regression.
