[FIX] web: properly loads default values for many2manys

Many2many default value can be a list of ids, and in that case, we did
not properly load data.

It could be seen by selecting a few contacts (in list view), then
opening the 'Merge contact' wizard in the sidebar (action menu).  Before
this commit, the wizard did show a list with some empty rows (for the
field partner_ids).
