fix(data-store): match claims by credential hash when deleting credential

[mirceanis]

What issue is this PR fixing

fixes #1269

What is being changed

When deleting a credential, the corresponding claims are matched by the credential hash (internally computed) instead of the credential id which is optional.

Quality

Check all that apply:

• I want these changes to be integrated
• I successfully ran pnpm i, pnpm build, pnpm test, pnpm test:browser locally.
• I allow my PR to be updated by the reviewers (to speed up the review process).
• I added unit tests.
• I added integration tests.

Details

I included the tests in the localJsonStoreAgent test suite as well to ensure similar behavior.
The @veramo/data-store-json did not manifest the same bug, but I added it to check for regressions.

This is a hotfix that should be release before the next major release
