[FIX] barcode: allow multiple buttons with the same string and action

Steps to reproduce the bug:
- Enable work order option in manufacturing settings
- Create a manufacturing order and use the product Table
- Open the tablet view
- with the JS instruction, try to simulate the scan of the command
`CONTINUE CONSUMPTION` with this value: `O-BTN.continue`

Problem:
The action continue is not executed because when the tablet view
is loaded, the function _barcodeButtonHandler is triggered in which
we try to call the `activeBarcode` function for all the buttons:

To add each button in a dictionary, we use as key the name + the string
of the button, but as multiple buttons can have the same name and
the same action, only the last button is saved:

Solution:
To allow having multiple buttons with a similar name and action,
we must add in the key the attrs hash of the button
