Fix for updates not being pushed out

[hirenj]

I noticed a bug where the updates weren't being forwarded to the sensor. You can see this when you insert an UUID into the PollenType objects when they're created, and look at which UUID is being used to send out the updates. This has also been discussed in #2

The very first run creates a UUID for the PollenType object 0409b222-11cc-4b3b-8700-4de58c5b8c29.

The next update creates a brand new PollenType (UUID efd1dd15-5d2c-4bf3-8bd3-44bbb8fd4afd), but the sensor ("Getting level from pollen type"), still references 0409b222-11cc-4b3b-8700-4de58c5b8c29.

To fix this, I've made the sensor objects not reference region objects and pollen objects directly, but instead it looks them up from the Pollen_DK object.

Any updates to this?
