Unit Tests for SynchronizeService

[Blue-B-code]

-Description
Here I've implemented a basic test for the SynchronizeService class. We used Robolectric to simulate an Android environment and access the application context, albeit within certain limitations.

-CheckLists
Unit Tests added :
handleUploadClaims_WithPendingClaims_DoesNotCrash – PASSED ✅

handleUploadClaims_WhenNoPendingClaims_BroadcastsNoClaimError – PASSED ✅

handleUploadClaims_WhenNoNetwork_BroadcastsError – PASSED ✅

processClaimResponse_WithError_UpdatesStatusToError – PASSED ✅

processClaimResponse_WithSuccess_UpdatesStatusToAccepted – PASSED ✅

processClaimResponse_WithRejectedClaim_UpdatesStatusToRejected – PASSED ✅

Similarly, for the Policies app, we had to change certain attributes or methods from private to protected to be able to mock them with Mockito.
