[FIX] web: can edit many2many_checkboxes with 40+ values

Before this commit, if the widget "many2many_checkboxes" was set on
a field with more than 40 values in the comodel (i.e. more than 40
checkboxes displayed), (un)selecting a checkbox that wasn't in the
first 40 checkboxes crashed. This was due to the default x2many
limit of 40: we only created a datapoint for the first 40 values,
whereas we could have up to 100 values to process (name_search
server-side limit). Note that this limit of 40 had no other impact
than limitating the number of records processed by the BasicModel,
the maximum number of checkboxes displayed being ruled by the
name_search server-side limit.

This commit ensures that all values returned by the server (at most
100 when this message is written) are processed and can be edited
as expected.
