[FIX] account, account_asset: account move views with assets

Since the recent css change, when going to Accounting menu then assets / deferred revenues / deferred expenses with a related bills / sales / expenses (if there is one click on it, a widget will open) the list view related assets (that is displayed when an asset_id is link) was too big for the view. By adding a colspan, the issues is solved.
