fix: enable tests in node that were not being included

[alanshaw]

@vasco-santos uses npm run test:node:core which runs tests in test/core/**/*.js and there were some tests failing.

CI runs npm test => npm test:node => which runs only mocha test/node.js.

...which requires only:

require('./cli')
require('./http-api')
require('./gateway')
require('./core/node.js')

and core/node.js requires only

require('./pin')
require('./pin-set')

NOT utils.js and others!!!

Lets see if they pass.

Hey @alanshaw , thanks for this PR.

Enabling the utils test lead to failling the resolvePath test.

I added a commit fixing those 2 tests. Basically:

objectAPI.get(rootHash, ...)

get was receiving as the first parameter the instance of the cid instead of its multihash.
