docker-credential-oskeychain 0.7.0 get fails to retrieve records

I've upgraded to version 0.7.0 of d-c-osxkeychain and can no longer retrieve records:

$ $A/docker-credential-osxkeychain version
0.6.4
$ $B/docker-credential-osxkeychain version
docker-credential-osxkeychain (github.com/docker/docker-credential-helpers) v0.7.0

$ for x in $($A/docker-credential-osxkeychain list | jq -r . | grep https | sed -e 's/ "//' -e 's/":.*//') ; do echo $x | tee /dev/tty | $A/docker-credential-osxkeychain get | cut -b 1-100; done

One difference is that when I run 0.6.4 I sometimes get that dialog prompting me for the keychain password. With 0.7.0 I never do. Maybe that's why it's failing

Start by reproducing the reported comparison between docker-credential-osxkeychain 0.6.4 and 0.7.0 using the version, list, and get commands shown in the issue. Investigate the macOS keychain retrieval path and the difference in password prompts; done means 0.7.0 retrieves the listed records successfully.
