Force the OAuth prompt when authenticating the GOOGLE_SHEETS for the first time

[fttx]

The refres_token is retrieved only the first time the app is approved in the google account.
If the user has approved the app on multiple computers, the second computer won't receive the refres_token (I guess).

Solution:

Conditionally add prompt: 'consent' to const authorizeUrl = oAuth2Client.generateAuthUrl({ access_type: 'offline', scope: GSheetHandler.scopes, }); when the local client hasn't ever been authenticated
