and without spaces for vat
[FIX] mail: message-id not parsed properly in message_route

[FIX] account: avoid to propagate context in send by email button

There is no reason to propagate the context in those buttons.

Besides, it leads to issues concerning the email template, rendering the wrong res_id because the active_id was wrongly propagated
[FIX] event: registration and confirmation template now have a domain on event.registration.
Otherwise all templates are displayed and this will lead to some issues.

Also added a description on event.registration, because currently its
displayed name is Email Thread.

[FIX] web: remove unneeded overflow-y on modal-body class

Will fix problem where opened dropdown list were hidden behind the modal footer
[FIX] orm.search_count: ignore `limit`, `offset` and most importantly `order`

These parameters are (or should be) irrelevant for
a search_count(), and they could actually break the
result or make it significantly slower (e.g applying
`order` on large tables).
This fixes a performance regression introduced by
0f43032b.

We could also raise an error offset/limit are
passed in combination with count, but that seems
unnecessary.

Also switched to "SELECT count(1)" for the count
query, as it is simpler and just as fast.
We'd get the same perf with * or any constant value,
as in "SELECT count('me in')", but let's keep it
simple ;-)
