Summary:
Removing `createNewConnection` method that was used in tests to create a
"scoped" version of `HomeDbManager`. Currently this won't work as there are
many methods (like `Users.findOne`) that are using the default (global) connection.
Additionally `HomeDBManger` had couple of bugs that were causing locks, which
manifested themselves in postgresql tests (that are not serializing transactions).
Repository methods like `Users.findOne` or `user.save()`, even when wrapped in
transaction were using a separate connection from the pool (and a separate
transaction).
Some tests in `UsersManager` are still skipped or refactored, as sinon's `fakeTimers`
doesn't work well with postgresql driver (which is using `setTimout` a lot).
Date mappings in `User` entity were fixed, they were using `SQLite` configuration only,
which caused problems with postgresql database.
Test Plan: Refactored.

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.

I make this change for then working on #870
