A little quality-of-life improvement: when a unit test fails, the test
runner now shows the line number. For tests with several assertions,
this is quite handy.

Before:
```
Client Error
assertion `left == right` failed
  left: "hello"
 right: "world"
postgres location: lib.rs
rust location: <unknown>
```

After:
```
Client Error
assertion `left == right` failed
  left: "hello"
 right: "world"
postgres location: lib.rs:22
rust location: <unknown>
```

As always, please install the latest `cargo-pgrx` with `cargo install
cargo-pgrx --version 0.17.0 --locked` and also update your extension
crate dependencies with `cargo pgrx upgrade`.
