fix(settings): Show loading spinner while searching accounts

Typing in the account search field briefly emptied the list and
displayed "No accounts" until the request returned, which on large
instances misled admins into thinking the query matched nothing. The
empty-state now keeps the loading spinner visible whenever the list is
empty and a fetch is in flight, regardless of whether it is the initial
page load or a subsequent search/group switch.
