One by one. Quantity input [Fix: Mobile behavior]

[ivanlopezluna]

What does this PR do? *

Fix poor behaviour on mobile when user needs to change item quantity.

It's not intuitive to change the value of the input since it cannot be empty, if the user wants to change the value from "1" to any other number, he must first put the desired amount and then he must remove the number "1".

How to test it? *
