Make server don't crash from non fatal errors.

[nathan130200]

I was testing sample server code. And i just had tried use /attach command with an entity selector, and server crashed

\flying-squid\src\lib\plugins\commands.js:11
     else setTimeout(() => { throw err }, 0)
                              ^

TypeError: Cannot read properties of null (reading '1')

Node.js v18.10.0

Instead propagate entire error, why just forward to error and clientError events as described in docs

UPDATE: I had to set unhandled exception hook in nodejs to don't close server:

process.setUncaughtExceptionCaptureCallback(err => {
    console.log('UNHANDLED ERROR: ' + err);
});
