    tdf#109045: store en calendar separately in OnDemandCalendarWrapper
    
    When working with pivot cache there's alternating use of
    locale dependent and locale indepentent formats, which
    causes unnecessary loading of calendars due to constant
    switching.
    
    OnDemandLocaleDataWrapper already does this, now do
    something similar in OnDemandCalendarWrapper.
