Fix: AllTestsAspectJ171 runs correct NewFeatures suite

While fixing #285, I noticed that *.ajc171.NewFeatures was never
executed as part of the AspectJ test suite, because since 2012 falsely
*.ajc1610.NewFeatures was imported and executed a second time instead.
In addition to an outdated AspetJ weaver library in 'lib', this was one
more factor why the regression bug was never spotted.
