`tabs_layout="start"` is broken

[bew]

I'm currently on branch v2.x at 2b2f748

With the config:

require"neo-tree".setup {
  source_selector = {
    winbar = true,
    tabs_layout = "start",
  }
}

I get:

The winbar is correctly set to %{%v:lua.require'neo-tree.ui.selector'.get()%}
and that function returns "%#NeoTreeTabInactive#%4009@v:lua.___neotree_selector_click@%…%<%0@v:lua.___neotree_selector_click@" (missing all tabs?)

@bew I just pushed a fix in #852. Could you have a look to see if it fixes the issue?

I tested your PR, works well with tabs_layout="start" 👍
