0030809: CalculateGross functionality may be called several times in parallel

Description

Currently in the Web POS there are several actions which may trigger the "calculateGross" functionality, which computes taxes and gross/net values of each line and the receipt.

This functionality is asynchronous, and should protect itself so that no more than one execution is happening in parallel, to prevent potential data corruption and performance problems. However, this is currently not the case.

Steps To Reproduce

- In the Web POS, add a product
- Click on the line, and click on the "+" button many times in quick succession. Verify that the browser slows down quite a bit, and that there are multiple executions of the calculateTaxes functionality running in parallel. This should not happen.

Proposed Solution

The calculateGross function should control whether there is an execution currently running, and should start a new execution if a call happened while the previous one was running.
