This fixes a common React warning we see. Most of these components should be using constructors instead, however componentDidMount is just as good (and doesn't require converting most of these).
Conversion to classes will be done in a later stage of React warning fixes.

A typo led to an event handler leak with the custom status labs feature. A new
handler would leak each time you change rooms, which can add up over the course
of a long-lived session.
This returns to the previous behavior of avatar only without a button when the
custom status feature is disabled so that you don't get pointer cursor for
something that does nothing when clicked.
The avatar ring spacing is kept consistent with and without the feature enabled
by using a different class in CSS.
Similar to changes in `StatusMessageContextMenu`, this changes to using the new
status message event emitted in js-sdk to simplify state handling for the avatar
ring when a status is present.
Adjusts the appearance of the avatar ring to match the latest comps.
In addition, we now always render the surrounding button element, which
simplifies styling since the same size is now occupied both with and without the
feature.
This improves alignment between text in the composer and text in the message
history (https://github.com/vector-im/riot-web/issues/8111).
