Revert "Remove JDT from dependencies for now"

a slow eclipse mirror. JDT download time is not very significant.

This reverts commit 56b44b8974f068e98d271216775706a0ea2ec638.

Turn tests on for Workbench tests
Resolve Configure Python dialog that locks tests
Turn on tests on org.python.pydev.refactoring
