Query string version of the homepage is not cleared with rocket_clean_home

Before submitting an issue please check that you’ve completed the following steps:

• Made sure you’re on the latest version
• Used the search feature to ensure that the bug hasn’t been reported before

Describe the bug
When rocket_clean_home is triggered, the cache of the query string is not removed.

To Reproduce
Steps to reproduce the behavior:

1. Add a query string to cache in the settings
2. Cache the homepage with query string domain.com/?test=123
3. Make sure that it's cached on the SFTP
4. Update any post to trigger the rocket_clean_home
5. Confirm on SFTP that the homepage is cleared but the #test=123 is not

Expected behavior
We should clear also the query strings versions, including the cache and ignored query strings. Probably just looking for directories starting with # in the root cache directory and passing them to rrmdir will be fine.

Reproduce the issue

I was able to reproduce the issue.

Root of the problem

We are not checking for folders starting with the # character when clearing the cache inside rocket_clean_home.

Scope a solution

We need to add a check for # starting folders in rocket_clean_home and delete them if they exist.
For that we can add this code to the rocket_clean_home method:

$param_dirs = glob( $root . '/#*'  );

	if ( $param_dirs ) {
		foreach ( $param_dirs as $dir ) {
			rocket_rrmdir( $dir );
		}
	}
