Queris fail when document properties are compared.

[kamnel]

Describe the bug The new linux emulator (cosmosEmulatorVnextPreview) is unable to execute queries that compare document properties. These queries work fin in Windows version of emulator

To Reproduce Steps to reproduce the behavior:

1. Start Comos emulator vNext
2. Add a database and collection using cosmos explorer
3. Add the following item

{
    "id": "d624842e-6753-47e6-9b42-5d78cfc7036a",
    "Name": "John Doe",
    "Type": "User",
    "UserId": "user0001",
    "TenantCode": "tenant1",
    "PrimaryTenantCode": "tenant1"
}

4. Execute the following query:

SELECT c FROM root c WHERE c.Type = "User" AND c.TenantCode = c.PrimaryTenantCode

5. The query does not complete and you get the error

Failed to query item for container users:

Expected behavior The query is supposed to complete successfully and the document added earlier is returned as the result.

Additional context The query SELECT c FROM root c WHERE c.Type = "User" where properties are not compared executes correctly, the issue appears to be when we try to compare document properties like SELECT c FROM root c WHERE c.TenantCode = c.PrimaryTenantCode
