[FIX] web: pivot correct context after reload

Open a pivot view with default filters automatically activating
Disable those filters

Change the groupBys on the rows and cols of the pivot

Save your result as a favorite filter

Before this commit, the filter did not contain the context information for columns groupby
Also, the search view did not exploit the context of the new filter as it should be

After this commit, the flow works as expected
