Modify the Error in Consultation form to be self explanatory

[nihal467]

Describe the bug

• When we create multiple patient consultations with same IP number, it throws an "Non Fields Errors - Patient number mustbe unique within the facility"

To Reproduce
Steps to reproduce the behavior:

1. Create consultation for multiple patient with same IP number
2. See error

Expected behavior

• error message should be self explanatory something like consultation with this IP/OP number already exists; it should be a unique value.

@nihal467 I tried to create 2 patient consultations with same IP number but they were created successfully. I did not encounter any error

@hrit2773 it needs to be in the same facility too.
