fixed path for trace-axios dependency

Bug found - "var connections = resp.data.data;"

This was not a bug afterall, reverting.

Typo found in "opts.linkUpPatientId;"

… to use shareous2, which does not work.

Align treatments syncing to last glucose for first pass.

In order to share this interface, between external and sidecars, it needs to
standardize on being a real date object when present.

This prevents a category of errors the plugin is running internally to
Nightscout but has no recent information to generate a reasonable last known
basis.
This allows minimed to sync treatments data specifically on last treatment data
when syncing from within Nightscout.

There is a potential issue with using 0 as the default here, as this could
create issues duplicating and syncing the largest amount of data that the
driver may allow.

Force Medtronic to log requests from nightscout-connect.
Do not allow plausible deniability.
Per nightscout/minimed-connect-to-nightscout#46, force
putting a second UUID in a header.  x-axios-tracing already sets a UUID.
This patch correctly uses browser based headers for processing and requesting
HTML Forms.

When it's possible to log in, fetching valid data should result in inserting
new data to Nightscout.  This patch adds needed control flow (returning a
promise), as well as corrects datetime handling in order to allow inserting
missing information into Nightscout.

If the word Nightscout is present in the UA string, Medtronic EU servers will block the request.
This patch moves the software attribution information to the x-powered-by
header.

x-axios-tracing already implements a uuid in that header, making this one
redundant.  This patch removes the x-uniq-req header, which does nothing but
otherwise complicate the code.

This patch refreshes existing Carelink session when possible, instead of always
creating new sessions.
Thanks @sbc2280 for the tip:

Refreshing the Carelink session involves using the right content-type, as well
as adding the relevant locale and country query parameters.
