fix exception when editting an empty MULTI_HEADER

In edit-message-mode, an exception is generated by pressing 'c' to edit the Cc
field when no value currently exists.  This is due to calling Array.join() on
nil.  This patch addresses the execption by forcing an empty array when the
current value is nil.
