[FIX] mail: fixes linkify for url with subdomain

__Current behavior before this commit:__
URLs that have a subdomain different than `www` and a domain name with
more than 13 characters are not properly linkified in the chatter.

__Description of the fix:__
The url regexp was changed with [0dc68dcc](https://github.com/odoo/odoo/commit/0dc68dcc94ab9bb2e47943967fa2bc31780d20fa)
to make punctuation mark the end of url to linkify. The 1st dot
removed in diff was a mistake. This commit reverts this part, so
that url above is correctly linkified while fixing the problem.
