reset notmuch Mailbox->size on opening

previous behaviour: size was not reset. This resulted in mailbox size to
accumulate on each mailbox reopening, hence displaying incorrect mailbox
size information in the status bar.

new behaviour: size is reset to zero.

steps to replicate previous behaviour: open neomutt with vfolder. Press
space to refresh vfolder (open from sidebar) several times. Mailbox size
in the status bar accumulates.
