CVE-2023-0614 s4:dsdb:tests: Fix <GUID={}> search in confidential attributes test
The object returned by schema_format_value() is a bytes object.
Therefore the search expression would resemble:
(lastKnownParent=<GUID=b'
00000000-0000-0000-0000-
000000000000'>)
which, due to the extra characters, would fail to match anything.
Fix it to be:
(lastKnownParent=<GUID=
00000000-0000-0000-0000-
000000000000>)
