[v4,10/11] t-reftable-record: add tests for reftable_ref_record_compare_name()

Commit Message

Chandra Pratap July 2, 2024, 7:22 a.m. UTC

reftable_ref_record_compare_name() is a function defined by
reftable/record.{c, h} and is used to compare the refname of two
ref records when sorting multiple ref records using 'qsort'.
In the current testing setup, this function is left unexercised.
Add a testing function for the same.
