PHP Fatal error: Trait "Drush\Boot\AutoloaderAwareTrait when installed on a site with Drush 12.x

Tested this with drush 12.1.2.0 , with site_audit module's version 4.0.0-rc1 and the issue was reproducible. The MR changes works fine and the module no longer shows any error.

Thanks @markdorison, your patch fixes the issue.

Raising Priority to Critical, since it can lock out the administrator, if Drush is the only method of logging in.

It's impossible to upgrade a site to D10 without this patch. Thanks for your help @markdorison

Thanks @jrglasgow, the latest version 4.0.0-rc3 released today works well.
