Cache flush should remove htaccess when push is enabled

If I enable the push feature for css/js, there’s an issue when the filename changes in the manual mode (not sure of automatic)

W3TC makes htaccess within every folder

Consider for example:

https://www.example.com/2019/04/12/test-post

If css changes and the minify cache is flushed the old htaccess still remains in:

https://www.example.com/2019/04/12/

This causes htaccess with two css files pushed and unnecessary bandwidth waste.
