Improve mock server:

- add support for mocked `fetch`
- add support for `active_test`
- add support for x2m `in` in domains
- add support for default values computed from a function
- implement a more natural "next id" compute
- allow initial data without ids
- ensure write and x2m commands integrity
- improve bad data/bad commands error messages
- always warn for failing RPC, not only in debug mode
- fix all existing tests that had inconsistency data

Other changes done in mail (or dependents) that are not just related to tests:

- remove `direct_partner` from formatter result
  ->`correspondent` can be computed from other keys, especially `members`

- fix `livechat_visitor` convertData
  -> only process if there is value

- add `current_partner` and `current_user_id` as `init_messaging` result
  -> easier to mock than session

- remove usage of `need_moderation`
  -> that was just a search indirection to `moderation_status`

- adapt `partner_id` -> `res_partner_id` key in `_notification_format`
  -> to be consistent with field name

- add name in result of `mail_partner_format`
  -> sometimes display_name is not the same

- remove usage of `is_moderator`
  -> that was just an indirection to `moderation_channel_ids`

This commit adapts tests following recent changes on the helpers.
The main change is that addMockEnvironment (and all functions using
it) are now async, as they need to wait for services to be started.

Before this commit, when downloading a pdf from the pdfjs viewer, the
name of the pdf was always 'document.pdf'.

Now, the correct name of the pdf is used when downloading the file.

Before this commit, the url for the src of the iFrame used
to display text files in the document viewer wasn't properly set,
resulting in the `model` argument to be invalid.

This commit fixes this issue.

This commit removes the field `datas_fname` from `ir.attachment` as
it was unnecessary and most of the time the duplicate of `name` or
`url`.

This commit fixes the document viewer: the document viewer
was altering the `type` key of attachment objects, this issue was causing
matching errors in some cases.

With this commit, the document viewer widget uses its own key `attachment.fileType`
to store the information that used to override `attachment.type`
