[FIX] web: re-evaluate column_invisible after onchange

Let's assume a form view with field A and B (a one2many list), with
a column with attrs column_invisible depending on A.

If the user sets A manually, everything works fine (the column is
hidden/shown directly). However, if A is updated by an onchange
(e.g. depending on the number of rows in B), it doesn't. This
rev. fixes that issue.
