[PATCH 1/4] t5516: fix test order flakiness

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <stolee@gmail.com>

The 'fetch follows tags by default' test sorts using 'sort -k 4', but
for-each-ref output only has 3 columns. This relies on sort treating
records with fewer fields as having an empty fourth field, which may
produce unstable results depending on locale. Use 'sort -k 3' to match
the actual number of columns in the output.
