#1550. Fixes scripted/join that broke with #1546

Name hashing is now turned on by default, so I’m changing the value for

it’s joined with name hashing analyses.
Fixes #1550. Turning off name hashing to test Ant style
Move notes item to compatibility implication
Run AnalysisTest without name hashing
Merge pull request #1551 from sbt/fix/1550
