Description

Batch api/@microsoft/microsoft-graph-client throws an error even when you have 2 different strings

In my outlook inbox there were 2 different emails with message ids: AQMkADI1NjdjOTA3LTA2MDctNDljNS1iM2JjLWI0YzFmOGVjYjEzMABGAAADaFuLVZilDkGMRMEras84mwcAJoSf1ZrISEGDUfN0NvJ3fgAAAgEMAAAAJoSf1ZrISEGDUfN0NvJ3fgACvV-2EAAAAA== & AQMkADI1NjdjOTA3LTA2MDctNDljNS1iM2JjLWI0YzFmOGVjYjEzMABGAAADaFuLVZilDkGMRMEras84mwcAJoSf1ZrISEGDUfN0NvJ3fgAAAgEMAAAAJoSf1ZrISEGDUfN0NvJ3fgACvV-2eAAAAA==

the only discernible difference between these 2 strings is the eAAA and EAAA but they are different nonetheless

Steps to Reproduce (roughly)

It seems like a message which is undeliverable sometimes produces a message id which is similar to the undelivered email

1. Have an email in the inbox
2. Reply to that email with imaginary recipients
3. You should now receive an undelivered email message in the same email thread
4. Extract the message ids on this thread
5. Batch them into an array with a structure like so

   
   [    {
      id: '<Msg_id1>',
      url: '/me/messages/<MSG id 1/$value',
      method: 'GET'
    },
    {
      id: '<Msg id 2>',
      url: '/me/messages/<MSG id 2/$value',
      method: 'GET'
    }
   ]

6. Pass this as a `POST` request to graph's `$batch` endpoint via the `@microsoft/microsoft-graph-client` npm library
**Expected behavior:** The batch request should be executed

**Actual behavior:** Library throws a message id should be unique error
