licenses.exceptions doesn’t work with licenses.clarify

[Jayman2000]

Describe the bug
If you specify a crate’s license with licenses.clarify and allow that license using licenses.exceptions, then cargo deny check license will fail. Here’s a deny.toml that causes the error:

[licenses]
default = "deny"
allow-osi-fsf-free = "either"
deny = [
    "OpenSSL",
]

exceptions = [
    { allow = ["ISC", "MIT", "OpenSSL"], name = "ring" }
]

[[licenses.clarify]]
name = "ring"
expression = "ISC AND MIT AND OpenSSL"
license-files = [{ path = "LICENSE", hash = 0xbd0eed23 }]

To Reproduce

1. Download this minimum reproduction project.
2. Extract it and cd to its directory.
3. Run cargo deny check license.

Expected behavior
I expected no warnings or errors.
