Repeated sync GETS even when no change in the server

[mahalakshme]

Steps to reproduce:

• env: prerelease, user_id: nupoork@apfodisha or utkarsh@lahi
• after login sync, sync again

• server call are made as mentioned above.
• now sync again
• similar server calls to groupPrivileges, programEncounters, enrolment, etc will be made which is unnecessary.

Acceptance criteria:

• Already synced data to mobile app, should not be got again from server for all entities.

Analysis details:

The above is because for some calls sync was retrieving data equal to lastModifiedDateTime as well.

Impact:

Considering everyday around 1900 syncs are made, 15 unwanted calls per sync translates to around 30k unwanted calls/day reducing load on server and like 2s sync time save.
