[FIX] web: list: correctly evaluate groupby modifier with m2o

Let's assume a <groupby> node in a list view containing a button
with an invisible modifier referencing a many2one field, e.g.

```
 <tree>
   <groupby>
     <field name="m2o" invisible="1"/>
     <button string="do it" attrs="{'invisible': [('m2o', '=',
False)]}"/>
   </groupby>
 </tree>
```

Before this commit, the m2o field was correctly read, but it's
value wasn't processed by the model, so the modifier wasn't
correctly evaluated.
