Remove ': salsa::Database' bound from two examples Two examples had a superfluous bound ': salsa::Database' that wasn't present in the `compiler` example. The `query_group` macro adds this bound automatically. This change can lead to a trailing `+` in the bounds list. I verified this is OK by running the examples and verifying that the production is allowed [per the Rust Reference](https://doc.rust-lang.org/reference/trait-bounds.html) 2021-12-30 11:01:52 +00:00			`pub trait Interner {`
