Before this commit:
Suppose invl1 of 1000.0 with 10.0% and invl2 of -100.0 with the same tax. A tax line of 90.0 is created.
If invl1 is created before invl2, the tax details is computing the tax amounts as:
invl1 tax amount = 1000/900 * 90 = 100 (OK)
invl2 tax amount = 90 - 100 = -10 (OK)
total tax amount = 100 - 10 = 90 (OK)
If invl2 is created before invl2:
invl1 tax amount = 100/900 * 90 = 10 (NOT OK)
invl2 tax amount = 90 - 10 = 80 (NOT OK)
total tax amount = 10 + 80 = 90 (OK)
