test: ipa: ipa_interface: Use IPAManager::createIPA()

The goal of ipa_interface is to unit test the IPA interface. It
currently creates the IPA proxy through the higher level PipelineHandler
class. Use the IPAManager::createIPA() function instead to keep the
focus on the components that were meant to be tested.
