Subject: [PATCH] [FIX] web: keep o2m current page in correct range when going
 through different form view records

For example, when being on page 4 of a o2m then switching to next form
view record, if this new record did not have 4 pages for this o2m, the
o2m was shown empty (and if there was no page, the o2m became unusable)
