test: Catch naked returns and check for canonically named imports

Browse Source 
This catches scenarios where we forgot to prefix the error with return.
One of our contributors occasionally made this typo, and since core go
vet didn't (surprisingly) catch it, we should add a test!

It also adds a simple check for import naming aliases. Expanding this
test to add other cases and check for differently named values might
make sense.
