Fix platform naming ambiguities

[andreiolaru-ro]

Loading of standard platforms gets names from the enum, but platforms may not override getName ().

Scenario: LocalPlatform does no override getName so it reports as being called default, but it is registered in Boot as local.

• [ ] check if a similar problem arises with names of agent loaders.

Fixing: exception should be thrown, at platform loading, if platform name is not the same with name in the enum.
