[FIX] web: do not use groupbys in views not groupable

Before this commit: Some problems occur with not groupable views (views for
which searchMenuTypes does not contain 'groupBy'):

    - The searchbar still displays autocomplete suggestions for groupby filters
    defined in the search arch while selecting one of them would cause a crash;
    - If the action has a default groupby (set in Studio for instance) then it
    is still applied and causes crashes.
    - Those problems happen in the documents kanban view for instance.

After this commit: If a view is not groupable,

    - The groupby filters coming from the search arch are not displayed at all
    in the interface;
    - A default groupby is never applied;
    - The search query generated in the control panel has groupBy = [].
