Improve query modification prevention in input-less mode

Browse Source 
fzf would restore the original query in input-less mode after executing
a chain of actions.

This commit changes the behavior so that the restoration
happens after each action to allow something like
'show-input+change-query(...)+hide-input'.

Fix #4326
