Move CarrierConfigLoader registrar call to init

Move the service register call so that the fake version of the
CarrierConfigLoader that is created during testing doesn't replace
the actual CarrierConfigManager during the duration of the test.

Also quit the handlerthread to avoid issues in the future.
