fix: BaseModel::insert() may not pass all the values from Entity (#4980)

* Update of BaseModel.php to fix INSERT issue

Applied the fix that enables the INSERT to work correctly when inserting a row that already contains data.

* Update BaseModel.php

* Added tests for fix.

User.php is an Entity
UserObjModel.php returns an entity not StdObj

* Updated to simplify usings.

* Updated to cleanup test code.

* Update tests/system/Models/InsertModelTest.php
