`ns.page.history.replace` превращает историю в каламбур

[chestozo]

Right now this is what we have:

ns.page.history._current = 'url3';
ns.page.history._history = [ 'url1', 'url2' ];

ns.page.history.replace('url4');

// This is what you get:
// ns.page.history._current = 'url4';
// ns.page.history._history = [ 'url1', 'url4' ];

// And this is what you SHOULD get:
// ns.page.history._current = 'url4';
// ns.page.history._history = [ 'url1', 'url2' ];
