Fix `getContextNameFromHash` edge case not returning the expected value about verida-js

[aurelticot]

@tahpot for this bug, I haven't tested or pushed any commit but here's my suggestion:

Note: Promise.any is es2021 so you'll have to update the tsconfig

  public async getContextNameFromHash(contextHash: string, didDocument?: DIDDocument) {

    // ... 

    const endpoints: ServiceEndpoint[] = <ServiceEndpoint[]>service.serviceEndpoint

    if (endpoints.length === 0) {
      throw new Error(`Unable to access any endpoints associated with context hash ${contextHash}`)
    }

    try {
      return Promise.any(endpoints.map(async (endpoint) => {
        const endpointUri = endpoint.substring(0, endpoint.length-1)  // strip trailing slash

        const consentMessage = `Obtain context hash (${contextHash}) for server: "${endpointUri}"?\n\n${did}\n${timestamp}`
        const signature = await this.account!.sign(consentMessage)

        try {
            const response = await Axios.post(`${endpointUri}/user/contextHash`, {
            did,
            timestamp,
            signature,
            contextHash
          });

          if (response.data.status !== 'success') {
            throw new Error(`Endpoint ${endpointUri} failed to return context name associated with context hash ${contextHash}`)
          }

          return response.data.result.contextName as string // TODO: Ideally should validate before returning to ensure the expected value type
        } catch (error) {
          throw new Error(`Endpoint ${endpointUri} failed to return context name associated with context hash ${contextHash}`)
        }
      }))
    } catch (error) {
      throw new Error(`All endpoints failed to locate context name associated with context hash ${contextHash}`)
    }
  }
