<refactor, test>(core, test): core improved and test gpg alone mode

1. let modules known their channels.
2. let factory create a channel.
3. reduce dumplicate code.
4. add type check for function object.
5. test gpg alone mode.
6. remove some asserts.
7. rename importexportor to importexporter.
8. move args in gpg context constructor to a struct.
