`didDht` Import issues

[chris-tbd]

I've been working with portable DIDs a lot and seemingly randomly run into this issue:

TypeError: Cannot read properties of undefined (reading 'uri')
 ❯ Function.<anonymous> node_modules/.pnpm/@web5+dids@1.1.1/node_modules/@web5/dids/src/methods/did-dht.ts:655:45
 ❯ node_modules/.pnpm/@web5+dids@1.1.1/node_modules/@web5/dids/dist/esm/methods/did-dht.js:7:71

 ❯ site/testsuites/testsuite-javascript/__tests__/tbdex/wallet/quickstart.test.js:34:42

In my latest case, I ran into this issue simply by changing the name of the input JSON. Example snippet:

let customerDidString = '{"uri":"did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo","document":{"id":"did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo","verificationMethod":[{"id":"did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo#0","type":"JsonWebKey","controller":"did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo","publicKeyJwk":{"crv":"Ed25519","kty":"OKP","x":"4dGQOFwyacipPH04UG1rULQkBc8h6jNOhLPMgvoUOgs","kid":"XPokllC3LZAVGizIL0naDdByQHeyY12uLJaXO4j46Nw","alg":"EdDSA"}}],"authentication":["did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo#0"],"assertionMethod":["did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo#0"],"capabilityDelegation":["did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo#0"],"capabilityInvocation":["did:dht:h8e3yqnhgjwhtkjhxwhfy5mmkn4nebqxr8idguwrsxgef6ow8efo#0"]},"metadata":{"published":true,"versionId":"1718740086"},"privateKeys":[{"crv":"Ed25519","d":"iTfn3Z8uPp3gTg-9LxQVZVODGqnP3M0UDjZiIwBEctc","kty":"OKP","x":"4dGQOFwyacipPH04UG1rULQkBc8h6jNOhLPMgvoUOgs","kid":"XPokllC3LZAVGizIL0naDdByQHeyY12uLJaXO4j46Nw","alg":"EdDSA"}]}'

       // Customer DID    
       const customerPortableDid = JSON.parse(customerDidString);
       customerDid = await DidDht.import({ customerPortableDid });

Seems very finicky and hoping to figure out what could be going wrong here
