feat: store only user ID in session

[jia1]

Closes #212

[karrui]

Might want to fix tests! Check that we do not retrieve the user id in session with the id modifier and stick to _id (but type checking should catch)

EDIT: I checked, no usages of id anywhere for the session user, now we just need to fix the tests

actually, in src/app/loaders/express/logging.ts, we have a getter for session.user._id for logging and that may break if we don't update that too

Don't need to do this, since we are just removing everything from session.user except for _id

[karrui]

should be ok now, just need to fix the build error (remove the user.email call (since session doesn't contain the full user anymore) and replace it with _id i guess))

also search the codebase for instances of TODO(#212) and remove them! :D

@karrui Do you mean the line containing: message: Successfully logged in user ${user._id},? Reference to .email was removed but pipeline still fails. Travis build gives me an empty screen.
