Issues:

1. Empty "Date Of Birth Verified" value causes a null pointer exception
2. If SubjectType registration location setting is not configured, "No matching location types found. If subject type has registration locations then only those will be used for matching." is always thrown even though valid location types exist.

documentation for reg., location

AC:

• "Date of Birth Verified" field should not be a mandatory field. If nothing input in this column, it should be considered not verified and hence false.
• If 'Location type where this subject can be registered' is not configured in the subject type, it should allow the subject to be registered via CSV at the lowest level. If not all addresses until the lowest is mentioned show the error "Mention all the locations in the location hierarchy needed to register the subject."
• If there are multiple location hierarchies and 'Location type where this subject can be registered' is not configured, then the subject should be allowed to be registered in any one of the two hierarchies. This is what is done/allowed when registering via mobile app

• If 'Location type where this subject can be registered' is configured, then that should be respected. If extra address levels are there in the CSV it should not fail.
• Add a tooltip on 'Location type where this subject can be registered', stating 'If this is not configured, subjects can be registered only at location type with the lowest level.'

Inputs:
