Search Stream request filters don't throw error if more than 20 000 items in IN clause.

[bdetry]

Google Ads API documentation says that the limit for filtering using GAQL query system it's 20 000 items in the IN clause and should return error FILTER_HAS_TOO_MANY_VALUES if the limit is exceeded. As you can see here.

In my case, I'm using a NOT_IN clause with more than 20 000 items in filter and no error is returned. It looks like instead of returning FILTER_HAS_TOO_MANY_VALUES it take the first 20k items of the filter and ignore the rest because I'm missing data. Actually, when I do the filter "manually" (with a loop in my code) I have all the results.

Here is the demonstration :

`var searchTerms = service.GetSearchTerms(request).ToList();

        var forFilterTest = searchTerms.Concat(searchTerms).Select(x => x.SearchTermView.ResourceName);

        var requestTest = new SearchTermRequest(452********, new TimeRange(DateTime.Now.AddMonths(-11) , DateTime.Now.AddMonths(-1)))
        {
            Fields = new List<string>()
            {
                "campaign.name",
                "ad_group.name",
                "metrics.cost_micros",
                "metrics.clicks",
                "metrics.impressions",
                "metrics.conversions",
                "metrics.cost_per_conversion",
                "metrics.conversions_value",
                "search_term_view.status",
                "search_term_view.search_term",
                "search_term_view.status",
                "segments.search_term_match_type",
                "ad_group.name",
                "campaign.advertising_channel_type",
                "search_term_view.search_term",
                "metrics.cost_per_conversion",
                "metrics.top_impression_percentage",
                "metrics.average_cpc"
            },
            Filters = new List<Filter>()
            {
                new Filter("search_term_view.resource_name" , Condition.NOT_IN, forFilterTest)
            }
        };`
