[FIX] base: Original bills on encrypted pdf

Steps to reproduce the bug:

-Let's consider two vendor bills VB1 and VB2
-VB1 and VB2 have both a PDF in attachment P1 and P2 respectively (the original bills from the suppliers)
-Let's consider that P2 is encrypted
- In the list view of vendor bills, select VB1 and VB2 and print original bills

Bug:

An error was raised because it is not possible to merge P2 with P1 as P2 is encrypted.
