Before this commit, the list's dataSources were managed by the core plugin
`ListCorePlugin`. This didn't make sense since dataSources aren't core data:
- they are neither exported nor imported
- they can be different for each user (their ids were generated via uuidv4
at import)
- managing them required to handle local command in the core plugin
Moved the dataSources management to the UI plugin `ListUIPlugin` and moved
the relevant getters inside this plugin. Changed the ids of the dataSources
to be the same as the list's id + a prefix, to avoid having to maintain a
mapping `listId` <=> `dataSourceId` .
This commit also removes the dataSourceId from the INSERT_ODOO_LIST
command, which have no place here since this is a core command and the
dataSources are now a pure UI concept.
