extract_datetime() returns 8 AM results in utterance where no time specification was made
forslund has backtracked this to lingua franca in [mycroft-core issue #2647](https://github.com/MycroftAI/mycroft-core/issues/2647)

> Found this while reworking the skill-reminder. While processing non timed reminder there is a safeguard mechanism to check [extract_datetime](https://github.com/MycroftAI/mycroft-core/blob/a6cb0c5258dbc34e7f80daf50ed751c87a40c61e/mycroft/util/parse.py#L145) in ["the case where padatious misses the time/date"](https://github.com/MycroftAI/skill-reminder/blob/b8dc13ec00bb0feb361deb58fd71080e98ed1325/__init__.py#L251) with the result of returning 8 AM and blocking the non timed reminder alltogether. (tested in german language. Phrase: "Erinnere mich an Meeting"; changed the vocab locally and tested it also with "Erinnere mich Meeting" with no difference)
