Fixing integration tests
- was not correctly testing if oncotree was running
* JOB_RUNNING was empty, even when job was actually running
* if JOB_RUNNING was empty, then attempted to query oncotree
* was timing out too soon, oncotree takes a long time to startup
* check for job running needed a sleep before it or no job was found
* break and exit with error if ONCOTREE is inaccessible (timeout)
- oncotree_to_oncotree.py
* cross_version_oncotree_translator.py renamed oncotree_to_oncotree.py
* variable TEST_ONCOTREE_VERSION_MAPPER_FILENAME didn't exist
* ONCOTREE_VERSION_MAPPER_TEST_SUCCESS was not tested at end
* expected output default_oncotree_file_converted.txt needed updating for UNKNOWN oncotree code
- added some comments
