pzserver hangs on startup asking for an admin password

When starting the server, I eventually end up in a situation like this:
```
pzserver | LOG : General , 1726515032194> 1,220,115,395> User 'admin' not found, creating it
pzserver | LOG : General , 1726515032194> 1,220,115,395> Command line admin password: null
pzserver | LOG : General , 1726515032194> 1,220,115,395> Enter new administrator password:
```
which then hangs.

I fixed this by modifying the start parameters to
```
startparameters="-servername ${selfname} -adminpassword ${adminpassword}"
```
