Deezer plugin - original date fields being set to 0000

### Problem
This is a follow up on a beetcamp bug which is also present in the Deezer plugin - https://github.com/snejus/beetcamp/issues/79
Essentially, when running an album import the original date fields get 0000 written to them if the Deezer plugin is used.

### Setup

* OS: Linux
* Python version: 3.14.6
* beets version: 2.13.0
* Turning off plugins made problem go away (yes/no): N/A, it is a bug in a plugin

My configuration (output of `beet config`) is:
