Potential hang on "IPFS is Starting"

Per @UnKnoWn-Consortium, two conditions exist that can result in Desktop hanging on "IPFS is Starting" - original issue is https://github.com/ipfs-shipyard/ipfs-desktop/issues/1723 for background:

1. Promise returned by `checkIfAddrIsDaemon` function at `config.js` does not resolve when the target address is occupied by another service that may or may not be responding to the test POST request; and
2. Selecting an alternative port via the prompt presented by the app does not alter the `api` file inside the `.ipfs` folder
