notmuch: return all siblings in threads

Notmuch threads can silently drop sibling messages during threading when
a thread has multiple "top level messages" (IE a thread where the root
is missing). Modify makeThread to return a slice of all encountered
siblings and add these as individual threads.

Note that the current implementation does not link these threads
together with a dummy parent node. This should be done in the future
when rendering of these types of threads is implemented
