test: enable linting for tests Enable linting for the test directory. A number of changes was made so all tests conform the current rules used by lib and src directories. The only exception for tests is that unreachable (dead) code is allowed. test-fs-non-number-arguments-throw had to be excluded from the changes because of a weird issue on Windows CI.

test: remove unnecessary assignments common.js needs to be loaded in all tests so that there is checking for variable leaks and possibly other things. However, it does not need to be assigned to a variable if nothing in common.js is referred to elsewhere in the test. The main tradeoff for this bit of code churn is that it gets the code base most of the way to being able to enable the no-unused-vars rule in eslint. (The non-tooling benefit is that it lessens cognitive load when reading tests as it is an immediate indication that none of the functions or properties in common.js will be used by the test.)
