Eeschema: fix infinite loop in replace all caused by previous find fix. 

* Only check for search cache update on close dialog event instead of every
  update of the find/replace view which caused an infinite loop when replace
  all was called.
* Check for dirty search cache for each find/replace event.
* Add code to save and restore last replace index on cache refresh.
