[FIX] web: pivot: correctly save and restore groupbys on rows and cols

On a pivot view expand a field in column
another one in row
Then put a domain in the search view
Save the whole thing (ir.filter) as favorite

Before this commit, the ir.filter was not saved the right way when a domain was present
(Let alone its restoration)
This was because of
- the internal default groupbys of the pivot model was not updated, and what we got in the params was overwritten
by what existed before
- a slight typo in the code made the row updated with the col values
