[FIX] web_editor: save the content without blur

When the only change in a form was made in the html editor, if the user
did not blur the editor, the content was not saved.

The reason is because the `urgentSave` in `basic_relational_model.js`
check if the record is dirty before the HtmlField had the time to update
the value to make it dirty since the commitChange in the HtmlField could
run promises before calling `update`.

To solve it, in case of urgent save, we update the value before any
asynchronous modification and re-update it after those modifications.

In order to have this strategy only on urgentSave and not on the
blur of the editor, the params `{urgent: true}` has been removed in
`_onWysiwygBlur` as it seems to not be useful. Another params will need
to be added if we want to keep that behavior on blur.
