[FIX] web_editor: fix automatic editor context for RPCs

With https://github.com/odoo/odoo/commit/55131b8f5becdd3d4776f4c3e7e4288a0b185706,
we automatically add the known editor context (containing lang,
website_id, etc) when using the `this._rpc` method. Some RPCs needed
however to explicitely not send a value from this automatic context...
but this was not correctly implemented. This can now be achieved by
using the `noContextKeys` key in the `this._rpc`'s *options* parameter.
