Consolidating common session errors into one easier to read message.

The following console logs show up regularly for me:

[session-file-store] will retry, error on last attempt: Error: ENOENT: no such file or directory, open '/Users/natalie.carey/projects/prototype-kits/companion-prototype-kit/.tmp/sessions/WSerxmSthkoRku_lXY6etQJT-wHExmxL.json'

It happens when you start two kits with the same service name, that's something that will come up more regularly for us than for most users but it's likely to come up for our users sometimes. It can be reproduce by running:

npx create govuk-prototype-kit --version=13.2.4 kit1
npx create govuk-prototype-kit --version=13.2.4 kit2
cd kit1
npm run dev
[visit the homepage of the kit in the browser]
[in terminal press ^c to close the kit]
cd ../kit2
npm run dev
[visit the homepage of the kit in the browser]

I've put in a new error message but I think that wording can be improved. To see the new message run:

npx create govuk-prototype-kit --version=alphagov/govuk-prottoype-kit#session-error-message kit1
npx create govuk-prototype-kit -- version=alphagov/govuk-prottoype-kit#session-error-message kit2
cd kit1
npm run dev
[visit the homepage of the kit in the browser]
[in terminal press ^c to close the kit]
cd ../kit2
npm run dev
[visit the homepage of the kit in the browser]
