MedplumClient constructor ignores accessToken

[rahul1]

Repro

• Log into Medplum app in browser
• Copy the medplum access token from local storage
• Create a Medplum client as follows

const medplum = new MedplumClient({
      fetch: async (url: string, options?: any) => await fetch(url, options),
      token: medplumToken 
    });

• Call medplum.graphql(SOME_QUERY)

Expected Behavior

Query completes successfully

Actual Behavior

Unauthenticated error

Workaround

Call medplum.setAccessToken, rather than using constructor parameter
