app_manager: prevent loading unnecessary RyuApps

don't load RyuApps which is just imported and not defined in the module.
for example, if we run the script "test.py" as shown below by

$ ryu run test.py

the past implementation loads and instantiates not only Test but also RyuApp
and DPSet. this patch fix this wrong behavior

test.py
===

from ryu.base.app_manager import RyuApp
from ryu.controller.dpset import DPSet

class Test(RyuApp):
    _CONTEXTS = {'dpset' : DPSet}
