support open_tree recursive toggle on root dir , not influence history

[v6cc]

I use this restore history

defx#do_action('cd', g:defx#_histories[-1][1])

and sometimes want to open_tree recursive on root dir , need

call defx#call_action('cd', ['..', 'open'])
call defx#call_action('open_tree', ['recursive', 'toggle']) 
call defx#call_action('drop')

history will become parent dir, but I just want to open, don't want to change history

Could you support direct open_tree recursive toggle on root, not influence history ?

@Shougo now defx#do_action('cd', ['..', 'open', 'nohist']) work ok , but defx#do_action('cd', ['..', 'open']) will get error
