[PATCH] Release memory allocated by internet_address_list_parse_string()

[Tomi Ollila]

g_object_unref() releases the memory of the InternetAddressList object
returned by internet_address_list_parse_string() -- when last (only)
reference is released, internet_address_list_finalize() will do cleanup.

When reviewing, see also gmime-2.4.25/gmime/internet-address.c (or older)
I tested this patch by entering:  notmuch show --format=mbox '*' | wc

Note that this fixes one potential memory leak only in case --format=mbox
as _extract_email_address is called only there.
