Namespace the assert library for old testing files (#1761)

It looks like some older test files were "unwrapping" the assert package
to the current context. I'm changing this because:

1. While it works, sometimes the linter flags this. I'm not sure why.
2. Other testing files don't do this. I want consistency.
3. The testify readme doesn't seem to recommend this approach. I rather
   follow their examples.
