Restructured integration tests in soap ui project and added new test for
invalid messages for save patient messages
Added new code to test a hl7 message for validity for save patient
messages
Added fixes to make the integration test run again
Save patient endpoint now returns the correct status code when it cannot
process a message.

Restructured the integration tests... again (these got overwritten last
time)
Allowed the exception strategy to print the stacktrace instead of just
absorb it.
Removed commented out code so that it doesn't 'rot'
Merge pull request #173 from jembi/restructure-integration-tests
