Reduce number of tests that create new did:dht DIDs (#860)

In several of the tests we were creating fresh `did:dht` identities before each test run.

In this PR most of the `createIdentity()` methods were moved into `before` instead of `beforeEach` and generating a new protocol URI on each run to differentiate counts, specifically on a remote.

Additionally some tests do not need a remote DWN at all, so a `did:jwk` was used.
