CRUD concurrency tests

Confira a branch do pull request dos testes CRUD, execute o NSS no modo multiusuário em localhost com as variáveis de ambiente listadas e execute test/surface/concurrency.test.ts. Comece pelos casos de concorrência que estão falhando e compare as respostas e os eventos de websocket-pubsub observados com as expectativas. Considera-se concluído quando a suíte passar, incluindo exatamente uma criação bem-sucedida e uma notificação para cada caso de PUT repetido.

See https://github.com/solid/solid-crud-tests/pull/47, check out that branch of the CRUD tests.
Run NSS in multi-user mode on localhost. Then:

export OIDC_ISSUER_ALICE=https://localhost:8443
export STORAGE_ROOT=https://alice.localhost:8443
export ALICE_WEBID=${STORAGE_ROOT}/profile/card#me

export USERNAME_ALICE=alice
export PASSWORD_ALICE=123
export CURL_RESULT_ALICE=`curl -ki $OIDC_ISSUER_ALICE/login/password -d"username=$USERNAME_ALICE&password=$PASSWORD_ALICE" | grep Set-Cookie`
export COOKIE_ALICE=`expr "$CURL_RESULT_ALICE" : '^Set-Cookie:\ \(.*\).'`

export NODE_TLS_REJECT_UNAUTHORIZED=0

./node_modules/.bin/jest test/surface/concurrency.test.ts
