office-addin-dev-certs: keeps adding new certs on mac

[gordonmleigh]

When the certificate has less than a day until expiry, the certificate verification step fails, and it adds a new certificate. The next time it tries to verify the certificate, it still sees the old certificate, and creates another new certificate.

This is how you are verifying certificates:

Office-Addin-Scripts/packages/office-addin-dev-certs/src/verify.ts

Lines 15 to 16 in 8b85647

	case "darwin": // macOS
	return `security find-certificate -c '${defaults.certificateName}' -p | openssl x509 -checkend 86400 -noout`;

The security find-certificate call finds the first matching certificate, which is the expiring one, even after a new certificate is added.

I have checked in some updates to scripts that manage the certs. They should be better about deleting expired and duplicate certs and looking for a valid one.
