…irst time using one of the SSO strategies available (#571)

Notes on this PR

• Users requires the action-permission CREATE_PROJECT as defined in server/config/environment/shared.js in order to be able to create a project (client side check only).
• This PR create this action-permission the first time a user logs in using one of the SSO strategies available.
• If an existing DB is used, returning users will not benefit from chance. Either 1) delete the content of the users collection or 2) Manually create an action-permission for the existing users in the collection action-permissions.
