[FIX] web: show names of many2one on default_get

Before this commit, some records in a list did not show the name of their
many2one fields.

This case occurs when the records in the list are created from a default_get,
and the records do not fit in a single page. In that case, the records in the
first page correctly display the names of their many2one fields, but not the
records in the other pages.

Fixes #24547
