[FIX] web: parsing of date with abbreviated month/day

When using the abbreviated month in the language
date format (`%b`),
e.g. `%d %b %Y`
in some languages, the parsing of the date
from this format to the database format (YYYY-mm-dd)
failed because of a dot `.` added from time to time
to the end of the abbreviated name
e.g., in French, `5 juil. 2016`

This is a bug of `moment.js` < 2.13.0,
handling badly this dot.
This is solved from `moment.js` 2.13.0,
thanks to the below revision
moment/moment@41fdb58572546740c3a840ebd36fbe9e1bcdc9cb
moment/moment#3078

Unfortunately, we cannot update this library to its latest
release in stable release of Odoo (e.g. 9.0),
as this is seen as an unstable change
(if some API changes occured in the given library)

Instead, if the parsing of the date fails with the
strict mode (meaning the date must respect the format
exactly), we perform a second pass without the strict mode,
so this dot will be ignored,
and the date can be correctly parsed.

The issue can be reproduced by loading the French language,
and setting `%d %b %Y` as date format, and then performing
an advanced search on a date field. The value of the date
in the advanced search will be empty without this revision
(for the months having more than 4 chars,
other than `mars`, `mai`, `juin`, `aout`).
