tauri: Tasks spawned with `async_runtime::spawn` don't execute when 3 sidecar commands have been executed

Describe the bug

Tasks spawned with async_runtime::spawn don’t execute when 3 sidecar commands have been executed.

To Reproduce Steps to reproduce the behavior:

1. Execute 3 Command::new_sidecar in the setup hook of the application, with an tauri::async_runtime::block_on wrapper.
2. Try to async_runtime::spawn, or anything that uses that (eg and async command).
3. The spawned task won’t execute.
