[FIX] web: write date without separator

Since fbbfa6d it's not longer possible
to write a date without separator (e.g., 0102 for 01/02/2019; 121298 for
12/12/1998;  02042018 for 02/04/2018), or a date without year (e.g.,
01/02 for 01/02/2019) in the datepicker widget.

In this commit we have decided to be as permissive as tempus dominus
that call moment.js with strict false. This allows moment.js to deduct a
date from a string in a more versatile way. This also allows a more
versatile autocomplete in the search views.
