User session constructor strips the trailing slash of the provided URL

[arozniak]

Describe the bug

The user session constructor strips the trailing slash of the provided URL.

import {ArcGISIdentityManager} from '@esri/arcgis-rest-request';

  const userSession = new ArcGISIdentityManager({
    portal: portalUrl,
    clientId,
    token,
  });

Since we need a portal URL with a trailing slash at the end (for the Enterprise implementation), we need to add the following hack to the code:

  const session = userSession as any;
  session.portal += '/';

Is this an expected behavior?
