Hello all,

Attempting to save a link in an Rmail buffer fails with the error
"Wrong type argument: arrayp, nil".

Attempting to save a link in an Rmail buffer succeeds if all headers
are shown (by pressing T to toggle the display).

Attempting to save a link in an Rmail summary buffer always fails with
the same error, even if all headers are shown.

The error occurs because org-rmail-store-link attempts to get the
Message-ID header with mail-fetch-field, then remove the angle
brackets with org-remove-angle-brackets. However, without showing full
headers, Message-ID is hidden, and (mail-fetch-field "message-id)
returns nil. When this is passed to org-remove-angle-brackets, the
error is thrown.

The attached patch remedies this by toggling on the full header display
before getting the Message-ID.
