Bug 26239: Do not format large negative numbers

At several places we got the following error if we use numbers too big
for Number::Format
Template process failed: undef error - round() overflow. Try smaller
precision or use Math::BigFloat at /home/koha/src/Koha/Number/Price.pm line 44

It make the app explodes.
The goal here is to handle these errors gracefully and easily.

We fixed it for positive numbers in bug 15770, but we neglected the case of negative numbers

Test plan:
- Add a manual credit to a patron of 100000000000000
- ISE!
- Apply patch
- Restart all the things

Works perfectly.
