openharmony-standard: Reintroduce onInit patch

This patch makes a lot of of test-cases able to pass with the current code.
The patch is only a workaround, and should be reverted as soon as we have a
proper fix for the timing related issues that are causing problems with getting
tests to pass in onShow() ace method.
