radicle/profile: Canonicalize during test — heartwood

Fixes test profile::test::canonicalize_home.

Since Home::new canonicalizes its argument (which is what the test wants to ensure), also canonicalize the expected value, which is especially important on Windows as the canonicalization is more complex than on Linux.

For example:

thread 'profile::test::canonicalize_home' panicked at crates\radicle\src\profile.rs:802:9:
assertion `left == right` failed
  left: "C:\\Users\\runneradmin\\AppData\\Local\\Temp\\.tmpMnNkr6\\Home\\Radicle"
 right: "C:\\Users\\RUNNER~1\\AppData\\Local\\Temp\\.tmpMnNkr6\\Home\\Radicle"

     // Checks that if we have:
     // '/run/user/1000/.tmpqfK6ih/../.tmpqfK6ih/Radicle/Home'
     // '/run/user/1000/.tmpqfK6ih/../.tmpqfK6ih/Home/Radicle'
     //
     // that it gets normalized to:
     // '/run/user/1000/.tmpqfK6ih/Radicle/Home'
