Extract common functionality of apply_autostash() into
apply_save_autostash() and use it to implement save_autostash(). This
function will be used in a future commit.

If attempt_only is not set then we wont get any message - is this 
intended? Previously we always showed the message when applying was 
successful

I'm a bit confused by the new message, perhaps the commit message could 
explain what attempt_only is used for and then I suspect the reason for 
this change will become clear
