Don't change HTTP error code when wrong data-partition-id throws exception
Repro steps:
- Supply unexpected values to the Data-Partition-Id header such as %3c%3e%22'%%3b)(%26%2b.
Expected: Error with HTTP Code 400 - Bad request
Actual: Error with HTTP Code 500 - Internal server error
Root cause: Currently an HTTP 400 from Partition service is being replaced by HTTP 500 by Entitlements service. In this PR, avoiding the replacment.
