[FIX] mail: fix race conditions, especially with scroll

The `_update` of some components must take place before the `_update`
of other (usually sibling) components that might directly influence their
layout. This is in particular the case for `_update` that are relying on height.

Prevent force save of scroll position if there are pending hints to adjust it,
and prevent pending hints from overriding new scroll value.

Prevent flicker with message date.

This should fix all known issues related to incorrectly saving or restoring
scroll position.
