fix(#410): Failed to reset all prices of the entity

[novoj]

The scenario is as follows:

1. entity has price A ('basic', 'CZK', id = 1)
2. I call setPrices method with collection of new prices where there is price B ('basic', 'CZK', id = 2) ... the price B should replace price A

I get exception:

ERROR Failed to index entity eP_380523CZ-45 in catalog milagro_cz due to: Price `💰 90752 in basic CZK ` with id `90752` cannot be added to the entity. There is already present price `💰 8473 in basic CZK ` with id `8473` that would create conflict with newly added price because their validity spans overlap.
io.evitadb.api.exception.AmbiguousPriceException: Price `💰 90752 in basic CZK ` with id `90752` cannot be added to the entity. There is already present price `💰 8473 in basic CZK ` with id `8473` that would create conflict with newly added price because their validity spans overlap.

The method sets entityBuilder.removeAllNonTouchedPrices(); but too late and nevertheless it's not taken into an account when doing the ambiguous check.
