case sensitive should not be checked during creating name

[arjunSussol]

Describe the bug

Patient duplicity alert is not generated if the duplicate name created with the different case.
For e.g. Arjun is not equal to arjun and duplicate name confirmation alert failed.

To reproduce

name_case_sensitive_issue.mp4

Steps to reproduce the behaviour:

1. Go to Vaccination
2. Look for an existing name
3. Try create duplicate name as above but with different case
4. No duplicity check alert generated

Expected behaviour

Arjun = arjun in the case of username/name, but not valid for password.
Duplicity check should be performed without caring about the case of the firstName and lastName

Proposed Solution

Leave if you don't know how to fix/implement. Edit this issue description and explain here if you know the best path of implementing the fix within the codebase.
