Brendan Ashworth 0df54303c1 test: common.js -> common
This commit changes many test styles to change all references
from require('./common.js'); to require('./common');.

The latter is much more common, with the former only being used in 50
tests. It is just a stylistic change, and it seems that `common.js` was
introduced by a rogue test and copied and pasted into the rest.

Semver: patch
