Bug fixes
Adding an external user to a project no longer fails - Previously, adding someone to a project as an external user failed with an "Unknown error occurred" message when more than one account existed with their email address. Every account with that email address is now added to the project, so the person reaches it with whichever account they sign in to. This is especially relevant for people who ended up with more than one account on the same email address - for example an email-and-password account alongside an SSO account, or separate GeoCloud Drive and the old Reality Cloud Studio accounts.
