Purpose:

Modify the default value for shouldSyncToRemoteService to be true instead of false.

Most users who use G6 / ONE with Nightscout want this to be true. Frequently, they forgot to enable it again when they switch transmitters. By making the default true, this issue will be solved.

Test

Build using this PR.
