Subject: [PATCH] Terminate `comint-password-function' tests

* test/lisp/comint-tests.el (comint-test-no-password-function,
comint-test-password-function-with-value,
comint-test-password-function-with-nil): refactor
(comint-tests/test-password-function): actually test
`comint-send-invisible' and inhibit inadvertent interactive query
