Context
HomeDBManager lacks of direct tests, which makes hard to make rework or refactorations.
Proposed solution
Specifically here, I introduce tests which call exposed UsersManager methods directly and check their result.
Also:
I removed updateUserName which seems to me useless (updateUser does the same work)
Taking a look at the getUserByLogin methods, it appears that Typescirpt infers it returns a Promise<User|null> while in no case it may resolve a nullish value, therefore I have forced to return a Promise<User> and have changed the call sites to reflect the change.
Related issues
I make this change for then working on #870
Access control for ConvertFromColumn in the presence of access rules had previously been left as a TODO. This change allows the action when the user has schema rights. Because schema rights let you create formulas, they let you read anything, so there is currently no value in nuance here.
Summary:
Move an important set of tests that were in our SaaS
repo for no good reason.
Test Plan: moving tests
