[PATCH v3 1/2] shallow: free local object_array allocations

["Samo Pogačnik via GitGitGadget" <gitgitgadget@gmail.com>]

From: =?UTF-8?q?Samo=20Poga=C4=8Dnik?= <samo_pogacnik@t-2.net>

The local object_array 'stack' in get_shallow_commits() function
does not free its dynamic elements before the function returns.
As a result elements remain allocated and their reference forgotten.

Also note, that test 'fetching deepen beyond merged branch' added by
'shallow: handling fetch relative-deepen' patch fails without this
correction in linux-leaks and linux-reftable-leaks test runs.
