[FIX] web: Properly handle default favorite filters

Before this commit, the default active favorite filter was determined by
its ID given by the control panel. These IDs start at index 0, meaning
that if a condition checks for the value of such an ID, it could be
false even though the ID and its filter exists.

Now the indexation starts at 1 to avoid such problems.
