dev: no icons form /whoami calls without icon_size

Calls to `/whoami` generally don't require app icons. Fetching icons of
the smallest size still incurs round-trip latency from the database and
S3, as well as additional delay for any retries due to failed icon
generation.

Although this is technically a regression in `/whoami`, the impact is
localized to Puter's desktop only because apps are not allowed to
receive taskbar icons.
