The datepicker lib has been updated to tempus dominus (BS4)
recently, but our code hasn't been adapted correctly to the
requirements of the new version of the lib. As a consequence,
the datepicker didn't close itself when the input was focused
out anymore.
This required a slight change in the DomainSelector widget as it
produced a crash when a focused datepicker widget is removed from
the DOM (before the datepicker is destroyed), e.g. by a call to
html() on one of its parent.
