Before this commit, the web client evaluated all modifiers
(readonly/invisible/required) in some cases, even if it only needed one
of them. This is clearly not optimal, and I even suppose that for large o2m,
it could even have a noticeable effect on web client perceived speed
This commit simply make sure that we evaluate only what we need in those
cases. Note that it is not really a testable improvement, hence the
lack of tests.
