revocation status not checked if expired

[jchartrand]

If a credential is expired, that throws an error here:

vc/lib/index.js

Line 359 in 5eeabad

_checkCredential({credential, log, now});

which isn't caught before the next few lines - which check status - can run.

So status doesn't get checked, but should. Otherwise the verifier UI can only show no status or status false, both of which are wrong and misleadingly.

I think we need to move the status check before the expiry check (i.e, before the _checkCredential call.

This should be done as part of digitalcredentials/verifier-core#3

Possibly fixed by verifier core
