imapnotify: switch to goimapnotify instead of node-imapnotify (#1675)
I also made some modifications to the systemd service to match the [AUR version](https://aur.archlinux.org/cgit/aur.git/tree/goimapnotify@.service?h=goimapnotify) of `goimapnotify`. In particular, restarting is useful in case a network failure causes `imapnotify` to exit - that shouldn't mean that it stops trying when the network comes back up.
