Testing "add members" randomizes the value type

[gunnar-rydberg]

When the tester generates the test to add a user to a group it incorrectly (pretty sure) randomly picks attribute type from ["User", "Group"]

Here's an example where the tester tries to add a user to a group using type=group,
My service corrects the type in the response but this later fails the test when comparing the data.
