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.

events: provide better error message for unhandled error Previously, in the event of an unhandled error event, if the error is a not an actual Error, then a default error is thrown. Now, the argument is appended to the error message and added as the `context` property of the error.
