When the `#[sqlx::test]` macro is imported using `#[macro_use]` such as
in the following example:
```rust
extern crate sqlx;
mod tests {
#[test]
fn something() {}
}
```
then the `#[test]` generated by the macro will refer to itself instead
of the standard Rust `#[test]` macro. This will cause `rustc` to
recursively expand it and produce the following error message:
```
thread 'rustc' has overflowed its stack
fatal runtime error: stack overflow
```
Instead, we can just refer to the standard macro by using its fully
qualified path.
This PR:
* Swaps `#[test]` usages in `#[sqlx::test]` for their hygenic path to
prevent recursive expansion alongside `#[macro_use]`
Closes #2017.
