Allow saving presence patterns that cover no weekday

The pattern editor disabled Save unless a weekday was selected, but an
all-empty weekday set is valid in the core model and the API, and
migration 9 produces one for a legacy all-absent schedule. Save now only
requires a name (plus a valid anchor date and a change to save).
