[minimed carelink] Nightscout-connect adds 0, when no up-to-date SGV data is available #21

Hi all, I just recently started using the nightscout-connect plugin, as I used xDrip as an uploader to nightscout before.

Today, I changed my sensor for the first time since starting to use nightscout-connect and I recognized, that the plugin adds data points to the database every five minutes with an SGV=0. I think that should not be.

In the following example, I fetched the recent 12 values by curl https://XXXXXXXXXX.my.nightscoutpro.com/api/v1/entries/sgv.json?count=12&token=XXXXXXXXXX

I'd rather expect the downloader to recognize, that there's no new data available and leave the DB untouched. This adding of zeros might lead to unexpected behavior of other software, that fetches nightscout data through the API (like my Garmin watchface).

Thanks for your time. Trenar
