New version is not working with TypeScript without esModuleInterop but there is no warning

[raszi]

Given the following TypeScript code:

import JiraClient from "jira-connector";
const client = new JiraClient({ host: 'jira.foo.bar' });

With version 2.16.1, when trying to compile without esModuleInterop it gives me an error:

$ npx tsc index.ts
index.ts:1:8 - error TS1259: Module '"/Users/ikaraszi/tmp/node_modules/jira-connector/index"' can only be default-imported using the 'esModuleInterop' flag

1 import JiraClient from "jira-connector";
         ~~~~~~~~~~

  node_modules/jira-connector/index.d.ts:8:1
    8 export = JiraClient;
      ~~~~~~~~~~~~~~~~~~~~
    This module is declared with using 'export =', and can only be used with a default import when using the 'esModuleInterop' flag.

Found 1 error.

Works fine when I add the option:

$ tsc --esModuleInterop index.ts
$ node index.js

After 3.0.0, there is no error at the compile phase but the compiled version is not working:

$ npx tsc index.ts
$ node index.js
/Users/ikaraszi/tmp/index.js:4
var client = new jira_connector_1["default"]({ host: 'jira.foo.bar' });
             ^

TypeError: jira_connector_1.default is not a constructor

And working when I add the compile option:

$ npx tsc --esModuleInterop index.ts
$ node index.js
