[Bug]: default session hit function logic is counter productive

[deven298]

Current Behavior

When the same session is passed in the adapt function. The default session function check_hit_session will return False if the session_id already exists cache_session_ids. Later, the get_scalar_data function will return None if check_hit_session return False for the existing session_id and skip checking the cache data.

Expected Behavior

Ideally, if session_id exists in the cache_session_ids then check_hit_session function should return True so the cached data is further evaluated based on similarity evaluation function and so on.
