Since the username refactoring, the username in the store could be
undefined when the join input was pre-filled from user.full_name,
because no keystroke was needed to populate the store.

This led to a 400 error on the request-entry endpoint whenever the
user joined without editing the pre-filled name.

Fall back to user.full_name when the store username is missing, so
the endpoint always receives a value.

Acknowledged as a somewhat wobbly fix, but ships as-is until the
underlying flow is reworked.
