**Impacted versions:**
9.0 (probably 10.0)

**Steps to reproduce:**
1.  Install `account_asset` module
2. Create a new asset.
3. Confirm asset
4. Click on generate entry button on any depreciation line. It generates an 'Unposted' journal entry (account.move)
5. Check line state, should be green = Posted.
6. Go to entries and delete the entry.
7. Check again the line state, still green = Posted, but the journal entry doesn't exists.

At `account.move.unlink()`, https://github.com/odoo/odoo/blob/9.0/addons/account_asset/account_asset.py#L402 is not called, then `move_check` remains = True
