[Unittest]: Complement remaining tests in apis/core/utils (open-mmlab#110)

* Add remaining tests

* Use another method to import

* try to fix ppl import error

* try to fix pyppl import bug 2

* try to fix pyppl import error 3

* try to fix pyppl import error 4

* Use test class

* remove ()

* lint

* add else branch
