Description

matchConnection in src/connection/enterprise.js throws a TypeError when an enterprise connection has no domains configured. Either connections without domains need to be filtered out or an undefined domain value should be handled.

  return l.connections(m, 'enterprise', ...strategies).find(x => {
    return x.get('domains').contains(target); // throws if domains is undefined
  });

Reproduction

1. Configure an enterprise connection (e.g. samlp or oidc) with no domain entries.
2. Initialize Lock as part of a third party client auth flow.
3. Type any email address into the email field.
4. Observe TypeError: Cannot read properties of undefined (reading 'contains') thrown from matchConnection.
