t1302: expect repo format version 1 for SHA-256

When using SHA-256, we need to take advantage of the extensions section
in the config file, so we need to use repository format version 1.
Update the test to look for the correct value.

Note that test_oid produces a value without a trailing newline, so use
echo to ensure we print a trailing newline to compare it correctly
against the actual results.
