"Could not remove base" error with CARGO_TARGET_DIR

[ensc]

cargo leptos watch fails when CARGO_TARGET_DIR is set. I tried recent master (b3a556a)

1. mkdir /tmp/test
2. cd /tmp/test
3. cargo leptos new --name project --git https://github.com/leptos-rs/start
4. cd /tmp/test/project
5. CARGO_TARGET_DIR=/tmp/test/.cache cargo leptos watch

Results in

thread 'main' panicked at src/config/project.rs:217:14:
called `Result::unwrap()` on an `Err` value: Could not remove base "/tmp/test/project" from "/tmp/test/.cache/tmp"
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Error happens at

cargo-leptos/src/config/project.rs

Lines 213 to 217 in b3a556a

	conf.tmp_dir = cargo_metadata
	.target_directory
	.join("tmp")
	.unbase(&cargo_metadata.workspace_root)
	.unwrap();

A similar issue was fixed already in #159 but appeared again in #200 as an additional config was added. I can try fixing it.
