HUE-6897 [oozie] Ensure that examples_dir exists before installing examples
Review Request #11139 - Created July 22, 2017 and updated
It's wrong to create examples directory, later than trying to load examples into this directory.
This may cause some issues, when Oozie examples installed earlier than any other examples (state, when no exmaples_dir exists).
So in this fix, I'm just moved "Get or create sample user directories" above "Load jobs" part.
