An instance of iCure SDK is initialized for working as a specific user in a single group.
However, the user credentials may match multiple users in different groups (but at most one per group).
If that is the case, this function will be used to pick the actual user for which the sdk will be initialized.
If true (default) the password of the user will be salted together with the application id before sending it to
the iCure backend for login or when changing the user password.
This is done in addition to the server-side salting of the password before storing them.
