Bootstrapper has no active children left - bootstrap has failed

Reproductions steps:

• Run a local test network
• Execute browser and connect to test network
• Approve authorisation request when prompted
• Run API playground, create an app, authorise it, and connect it to network using loginFromUri
• The first connection should be successful
• Run loginFromUri again and it should fail with a -2000: Unexpected (probably a logic error): Could not connect to the SAFE Network in API playground client and a Bootstrapper has no active children left - bootstrap has failed in the terminal running the browser.
• Then execute another application, like web-hosting-manager, and it should successfully connect to network and you'll observe a 5th client connection in the safe_vault --first terminal.

I'm still experiencing this error after running at least 8 nodes, I tried 25 as well, and making sure that white listed config properties are null and not [ ].

For reference:

safe_vault.crust.config
{
  "hard_coded_contacts": [],
  "whitelisted_node_ips": null,
  "whitelisted_client_ips": null,
  "force_acceptor_port_in_ext_ep": false,
  "dev": {
    "disable_external_reachability_requirement": true
  }
}

safe_vault.routing.config
{
  "dev": {
    "allow_multiple_lan_nodes": true,
    "disable_client_rate_limiter": true,
    "disable_resource_proof": true,
    "min_section_size": 10
  }
}

safe_vault.vault.config
{
  "dev": {
    "disable_mutation_limit": true
  }
}

I can successfully create another connection in the API playground if I create a new app, by changing the name and vendor credentials, etc.

Why this is an issue is because developers need to refresh a tab when testing code, which might consist of connecting an app to the network, which has already been connected.
This is not the case on Alpha 2. A dev can run loginFromUri multiple times on the same URI without error.
