Subject: [PATCH] feat(typeahead): handles min-length of 0

keep typeahead popup open even when all input has been deleted. Still uses a default value of 1 for backward compatibility (when min-length is falsy but not === 0).

see [#3600](https://github.com/angular-ui/bootstrap/pull/3600) and [commit](https://github.com/angular-ui/bootstrap/commit/a5a25141fc88e642b84e135796daaf77dc653273)
