BookmarkManager: Update parent id immediately when calling navigateTo()
When removing a leaf node on bookmark tree, navigateTo() is called.
From navigateTo(), `window.location.hash = id;` does not immediately update bmm.list.parentId.
Because this, `chrome.bookmarkManagerPrivate.canPaste` is called with old parentId.
To fix this, manually immediately update bmm.list.parentId.

TEST=manual(create a leaf node, delete and see there's no console error)
