[PATCH] lib: Fix name reordering to handle commas without spaces

[Adam Wolfe Gordon]

Notmuch automatically re-orders names of the format "Last, First" to
"First Last" when the associated email address is
First.Last at example.com. But, if a name is of the format "Last,First"
then notmuch will format the name as "irst Last". Fix this by checking
for a space when doing the reordering.
