refactor(paroxysm): Explicitly macro imports, no more 'extern crate' r/1542

Removes all but one occurence of `extern crate`, to conform with Rust
2018.

The last one is necessary because Diesel is a giant jungle of
complicated macros re-exported from private crates, and the current
version makes it hard to import those directly instead.
