Describe your use case and the problem you are facing

I have been reviewing the code of the wp rewrite structure command and have run into unused $new_assoc_args variable , which looks like a residuum after past code updates:

rewrite-command/src/Rewrite_Command.php

Line 163 in 377b731

$new_assoc_args = [];

The variable was introduced in 3be1d98 where \WP_CLI::launch_wpcli was used for launching the flush command.

But it was later changed to WP_CLI::runcommand ( in bf6c7c0 ) which does not accept the assoc args param, and the --hard flag is being appended to the $cmd.

Keeping the $new_assoc_args variable in place makes the code less readable.

Describe the solution you'd like

Removing the $new_assoc_args variable definition and the only other usage in the code, as the variable is never really used:

rewrite-command/src/Rewrite_Command.php

Line 163 in 377b731

$new_assoc_args = [];

rewrite-command/src/Rewrite_Command.php

Line 167 in 377b731

$new_assoc_args['hard'] = true;

I'm happy to open a pull request, if we agree that this issue is valid.
