fix(dashboard): explicitly state none found

[bryson-g]

resolves #1293

• The previous implementation only checked if pages.length == 0, which did not accurately display when there were no search results found. This is because the pages object is the type of SearchResponse[], and at least one SearchResponse object will always be populated in the array, so it would never == 0. The more accurate implementation would be to check if ?.results.length == 0 for every response within the array.
