BsNav LinkTo @current-when support

[mwalper]

Hi,

the linkTo Component from navigation doesn't seem to support @current-when to display active state.

Is there a downside on just using a normal <LinkTo class="nav-link"..> inside Nav.item?
Or is there another way of doing it?

Seems like that argument is not passed through:

ember-bootstrap/addon/components/bs-link-to.hbs

Lines 1 to 10 in 6cf8edc

	<LinkTo
	@route={{this.route}}
	@models={{this._models}}
	@query={{this._query}}
	@disabled={{@disabled}}
	class={{@class}}
	...attributes
	>
	{{yield}}
	</LinkTo>

PR fixing it is welcome.
