fix: address edge case when getting DIDDoc component

[nickreynolds]

What issue is this PR fixing

fixes #1364

What is being changed

The getDIDComponentById function in did-resolver/src/resolver.ts is modified so that it correctly finds the result when the didUrl passed in is a keyID without the DID prefixed to it, but the resolved DID Document lists the key with the prefix.
