- Removed usages of algorithm.Securities.key as a parameter for the `ManualUniverseSelectionModel()` since those securities, added through `AddXXXX` calls will be managed by the `UserDefinedUniverse`. This was causing for Universes to try to add the same subscription requests - Adding new empty constructor for ManualUniverseSelectionModel, required for Python - ManualUniverse will return any existing SDC for the symbol. This is for maintaining existing behavior and preventing breaking changes: Specifically motivated by usages of Algorithm.Securities.Keys as constructor parameter of the ManualUniverseSelectionModel, since those Symbols added by Addxxx() calls will already be managed by the UserDefinedUniverse - Making some format modifications to aling with used Lean formatting
