[Zhang Qiang]

In the original implementation, pkcon refresh only refresh/build
metadata, while solv file have not been refreshed properly. this patch

Reference zypper's implementation, changed refreshMetadata flag from 
RefreshIfNeeded to RefreshIfNeededIgnoreDelay, or refresh will not 
work properly.
