[FIX] web: headless search views are ready from start

function start, line 783, filters_ready waits for fields_view_get deferred to be resolved before calling prepare_filters, which prepare the view filters.

The thing is that, at line 416, if this.headless boolean is true, the searchview is marked as ready (by resolving the this.ready deferred), and the fields_view_get deferred will never be resolved, as it is resolved in the else case, where the this.headless boolean is false.

Therefore, in this.headless true case, this prevents the deferred $.when(this._super(), filters_ready) to be resolved, as the deferred filters_ready will never be resolved. Therefore, the deferred returned by the start function is never resolved, and the searchview will never be regarded as ready neither.

In views.js, the ViewManager is marked as ready when the deferred manager_ready = $.when(searchview_loaded, main_view_loaded, this.view_completely_inited) is resolved. In the this.headless true case, as the searchview is never marked as ready, the manager isn't neither.

This leaded to some issues, like the action buttons in form views being disabled on click, and never re-enabled once the action/wizard executed. See opw-610723
[FIX] web: return _super deferred in start method

Forget to include the _super method in the deferred returned by the start function of the search view
