Fix NPE in AsyncFragmentLoader for 'already loaded' fragments.

AsyncFragmentLoader makes the assumption that fragment loads are always
initiated by runAsync() call, however Inbox uses an 'already downloaded'
download strategy whereby a server-side linker concatenates needed modules to
be preloaded onto the output. This means the onLoad() call is invoked without
a corresponding startFragment call.

This mostly works, except for the leftovers fragment, wherein a queue variable
is lazily initialized and deferenced early.
