[FIX] web: datepicker fallbacks to default english locale

When using the datepicker with norwegian locales, the dates are
correctly formatted using the norwegian locale but the name of
the months are shown in english. This cause a date validation
error and thus it is not possible to change the date.

tempusdominus.js uses moment.js to deal with dates, it sometimes
copies/creates some and set their option according to the ones
given at instantiation time and fallbacks on default options for
that are not set.
