IDE retrieval takes ~30 seconds or often fails

I'm not able to see a list of IDEs after a pick a workspace. This often happens when a template already has an IDE installed.

I noticed this against `dev.coder.com`.

```sh
java.lang.Throwable: Could not resolve any IDE for workspace hello1.main. Reason: com.jetbrains.gateway.ssh.deploy.DeployException: Worker binary deploy failed: check command log for details: Should not use empty paths

Comienza en CoderLocateRemoteProjectStepView.kt:166, donde se registra el fallo notificado, e inspecciona el flujo de recuperación del IDE y el registro de comandos en torno al error de despliegue por una ruta vacía. Reproduce el problema con un espacio de trabajo cuya plantilla ya tenga un IDE instalado. Se considera completado cuando la lista de IDE aparece de forma fiable sin el retraso de aproximadamente 30 segundos ni el fallo de despliegue.
