Lower codecov target for PR

Codecov or kcov or rustc changed the way they report lines, and closing braces
on their own line are now reported too. This add a lot of untested lines, in panic!ing
test cases or on error conditions:

```rust
if test_something() {
    panic!("Argl");
}  // <= this line is now reported as not run
```
