Code suggestion API might respond with empty suggestions, which are not shown to
a user. However previous implementation of telemetry incorrectly marked those
suggestions as shown. This commit checks if there is any suggestion to be
shown, and if not reports suggestion_not_provided event

refactor(telemetry): Stop reporting show events for empty suggestions
