fix: database for default configuration not initializing properly

[kosciolek]

Databases for all configuration names are created here: https://github.com/AxaFrance/react-oidc/blob/3e535c94dc57d59956498bfa0ca9536106039bda/packages/react/service_worker/OidcServiceWorker.ts#L288

Before a database is created, there's a check whether it already exists: https://github.com/AxaFrance/react-oidc/blob/3e535c94dc57d59956498bfa0ca9536106039bda/packages/react/service_worker/OidcServiceWorker.ts#L282

But the default database exists since the start: https://github.com/AxaFrance/react-oidc/blob/3e535c94dc57d59956498bfa0ca9536106039bda/packages/react/service_worker/OidcServiceWorker.ts#L41

Which means it won't get properly initialized, so if you do something like this in TrustedDomains.js:

const trustedDomains = {
    default: { domains: [ /* some domains */], showAccessToken: true }
}

the database for default won't show the access token anyway, since it's already initialized to hide the access token:
https://github.com/AxaFrance/react-oidc/blob/3e535c94dc57d59956498bfa0ca9536106039bda/packages/react/service_worker/OidcServiceWorker.ts#L50

I'm not 100% sure that it won't break something else (it seems not to!), but perhaps a maintainer could take a look.

Thank you so much @kosciolek !
I may wait another big pull_request merge before your.
It may create some conflicts because all files will move.
