Since 0ce02e2f (credential/libsecret: store new attributes, 2023-06-16)
a test that stores empty username and password fails when
t0303-credential-external.sh is run with
GIT_TEST_CREDENTIAL_HELPER=libsecret.
Retrieve empty password carefully. This fixes test:
ok 14 - helper (libsecret) can store empty username
