Litunanian day names in calendars with weeks not starting on Monday

In the Lithuanian localization the weekday names logic is different for the full day names and the shortened day names due to declination. This is ok when the Lithuanian weekdays numbering is used (week starts on Monday). However, when a calendar is used where the week starts on another day, the full weekday names are shifted (the abbreviated names stay correct). 

The change uses the isoWeekDay for the weekday name declination.
