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
(bug#38825).
