az rest --headers not taken into account when $expand'ing Microsoft Graph API

## Describe the bug

When querying the Microsoft Graph API utilizing the `$search` parameter a special header needs to be set (see error message). When additionally applying `$expand` the correctly provided header does not seem to be taken into account anymore.

**Command Name**
`az rest`

**Errors:**
```
Bad Request({"error":{"code":"Request_UnsupportedQuery","message":"Request with $search query parameter only works through MSGraph with a special request header: 'ConsistencyLevel: eventual'","innerError":{"date":"2023-05-26T07:16:39","request-id":"...","client-request-id":"..."}}})
```

## To Reproduce:

```
$select = '$select=displayName'
$filterTest = '$search=\"displayName:MySearchString\"'
$expand = '$expand=appRoleAssignedTo'
```

✔ Works:

```
az rest `
--method GET `
--headers ConsistencyLevel=eventual `
--uri "https://graph.microsoft.com/v1.0/servicePrincipals" `
--url-parameters $filterTest $select
```

❌ Does not work because of adding `$expand`:

```
az rest `
--method GET `
--headers ConsistencyLevel=eventual `
--uri "https://graph.microsoft.com/v1.0/servicePrincipals" `
--url-parameters $filterTest $select $expand
```

`--verbose` shows that the header is set correctly.

## Expected Behavior

Should work with `$expand`ing as well.

## Environment Summary

## Additional Context

Maybe `$expand`ing leads to subsequent requests where the header is not being forwarded to anymore?
