[PATCH 06/11] t-reftable-record: add reftable_record_is_deletion() test for ref records

[Chandra Pratap <chandrapratap3519@gmail.com>]

reftable_ref_record_is_deletion() is a function defined in
reftable/record.{c, h} that determines whether a ref record is of
type deletion or not. In the current testing setup for ref records,
this function is left untested.

Add tests for the same by using the wrapper function
reftable_record_is_deletion().
