[FIX] web_editor: set the clientId after creating it

Before this commit, when creating a new record, there is no
`_currentClientId` set in the wysiwyg as there is no collaboration
setup for new records. When the user save the record, there is a call
to `Wysiwyg.resetEditor` but as the
`OdooEditor.collaborationSetClientId` was called before
`Wysiwyg.setupCollaboration`, the `_currentClientId` was not set.

That lead to the `OdooEditor._collabClientId` being undefined, which
lead `OdooEditor.serializeNode` to not serialize the node through the
function `serializeNode`.

So unless the client A reload it's page, if another client (B) open
the same record and synchronize with client A, client A will send it's
history when `get_history_from_snapshot` is triggered but no
`_historySteps` mutations nodes will not be serialized.

So when client B will receive the steps in `historyResetFromSteps`,
the code will crash.

After this commit, the proper order will set the _currentClientId in
time because `collaborationSetClientId` is set after
`setupCollaboration`.
