[FIX] web: use read to update record values after resequence

Commit:
https://github.com/odoo/odoo/commit/818c18e55d0718286ff5bf332186a10f4d7a58ef
Updated the resequence logic in a way that was almost falser than before.
The added test however did work by coincidence, as index values were equal to
the sequence field values.
To be sure that we synchronize with what happens on the server, we do a read
after the resequence.
Additionnally, we take into account the result of the server resequence return;
if it is false, it means no resequencing happened, so we should not do a read.
