Creating access-log with use-server-log=true fails with IllegalArgumentException: Parameter 'abstractPath' may not be null

Steps to reproduce:

1. Download the Jakarta EE 8 Full & Web Distribution ZIP from https://www.wildfly.org/downloads/ 
2. Unpack it somewhere
3. Start the server via bin\standalone.bat
4. Execute the following command: bin\jboss-cli.bat -c /subsystem=undertow/server=default-server/host=default-host/setting=access-log:add(use-server-log=true)
5. You get the following error:

   {
       "outcome" => "failed",
       "failure-description" => {"WFLYCTL0080: Failed services" => {"org.wildfly.undertow.host.access-log.default-server.default-host.access-log" => "Failed to
   start service
       Caused by: java.lang.IllegalArgumentException: Parameter 'abstractPath' may not be null"}},
       "rolled-back" => true
   }

This works in 23.0.2.Final.
