test(e2e): read the glucose journey's list filtered to glucose

The journey counted glucose rows on the unfiltered list, which shows
the account's newest page of every type. Other specs keep writing
readings to the same account, so on a database a few runs old the
reading typed for yesterday fell off that page and the count read one
short. The list now opens with `?type=BLOOD_GLUCOSE`, so it holds
exactly the rows the spec owns.
