0022336: Compount Taxes don't applied properly in web pos

Description

If we have a tax that is composed by two simple taxes in cascade (for instance), the Web POS doesn't calculate the tax rate operating the two taxes. It just takes the rate of the tax that is marked as summary. Then, this one could have the field rate at 0.00 (that field is hidden when selecting summary) and as a result, the tax taken in the web pos is 0%

This behavior is correct if the POS Order is created directly in the ERP.

Steps To Reproduce

Go to an environment with White Valley data:
1) Create a tax called BCN and mark it as summary (leave the rate field at 0). Select Country Spain, region Barcelona. Leave blank destination country and region
2) Create 2 simple taxes, one of 5% and the other of 9.50, mark this last one as cascade. Select in both taxes country Spain, region Barcelona. Leave blank destination country and region
3) Create a tax category and associate the three taxes to this tax category
4) Choose a product and associate that tax category

5) Go to Sales Order and select organization Vall Blanca. Select any customer. Go to lines and select the product you associate the tax category before. See the tax selected in the line is BCN and the correct VAT is applied (see in tax lines 2 lines are added, one for 5% and other for 9.50)

6) Do the same but from WEB POS, see that tax applied is 0% rate. When it is imported to the ERP is shows BCN tax and rate 0% (so it doesn't take into account it was a compound tax)
