oeqa/sdkext/context: Work around broken dependency checks to get sdk tests running

This is admitted a bit of a hack but it does allow a number of significant sdk
tests to run successfully and hence improves testing of eSDK which is good.

I'm therefore proposing we do this until we come up with a better solution
since the current lack of testing is worrying and would have caught other issues
had it been present.
