Override message for empty tabs

When using org.civicrm.hrident (or similar custom-data-based extension), one adds a tab to the "View Contact" page which is based on a profile-form's data-table. If the table is empty, it displays this message:

"No multi-record entries found. Note: check is Include in multi-record listing property of the fields you want to display in listings"

In this scenario, it's normal & expected that a contact has an empty list, and the phrase "multi-record entries" is weird.

Preferred solution:

1. Change the generic error to something like 'No records of type "%1" found.' (%1 is the displayable name of the custom-data group). Example: 'No records of type 'Medical & Disability' found.'

If there's some significant problem with that solution, then we can consider alternatives like:

2. Allow each profile form to define its own error message.
3. Allow a hook to decide the error message.
