lorri daemon fails with "No such file or directory (os error 2)", but lorri watch succeeds

[avh4]

Describe the bug

The lorri daemon fails to build my project's environment, saying "No such file or directory (os error 2)" in the logs. But running lorri watch successfully builds it.

To Reproduce Steps to reproduce the behavior:

1. Start journalctl --user -u lorri.service --no-pager -f to monitor the lorri daemon log
2. In a separate terminal, cd into the project using lorri
3. The lorri daemon log shows an error

   Jul 28 01:12:50 host lorri[358780]: Jul 28 01:12:50.503 INFO build status, message: BuildEvent(Started { nix_file: NixFile(AbsPathBuf("/home/avh4/workspace/music/shell.nix")), reason: PingReceived })
   Jul 28 01:12:50 host lorri[358780]: Jul 28 01:12:50.503 INFO build status, message: BuildEvent(Failure { nix_file: NixFile(AbsPathBuf("/home/avh4/workspace/music/shell.nix")), failure: Spawn { cmd: "\"nix-instantiate\" \"-vv\" \"--add-root\" \"/tmp/.tmpedU3ei/result\" \"--indirect\" \"--argstr\" \"runTimeClosure\" \"/nix/store/69pg642v7d9s1z0nb0i3n2jynkmjkd9n-runtime-closure.nix\" \"--argstr\" \"src\" \"/home/avh4/workspace/music/shell.nix\" \"--\" \"/home/avh4/.cache/lorri/cas/de251a4170888ea8b8fb1ece0590735a\"", msg: "No such file or directory (os error 2)" } })
   

4. Run lorri watch in the project directory (it succeeds)

   Jul 28 01:14:59.356 INFO build message, message: BuildEvent(Started { nix_file: NixFile(AbsPathBuf("/home/avh4/workspace/music/shell.nix")), reason: PingReceived }), nix_file: /home/avh4/workspace/music/shell.nix
   Jul 28 01:15:04.476 INFO build message, message: BuildEvent(Completed { nix_file: NixFile(AbsPathBuf("/home/avh4/workspace/music/shell.nix")), rooted_output_paths: OutputPath { shell_gc_root: RootPath(AbsPathBuf("/home/avh4/.cache/lorri/gc_roots/96cf60f25c1bca4f0bab7e20322abdeb/gc_root/shell_gc_root")) } }), nix_file: /home/avh4/workspace/music/shell.nix
   

Expected behavior

The lorri daemon build should succeed.
