Add test for build with updated bundle versions

[fipro78]

This adds a test that

• first builds the pde-automatic-manifest demo project
• then updates the version of the whole demo using the tycho-versions-plugin
• then checks if the build succeeded
• finally reverts the version update

I think you don't need a new verifier here just reuse the one from above.

finally reverts the version update

As you should get a copy for the test i don't think this is required?

@fipro78 for some reason this now has compile errors :-\

[fipro78]

It somehow has changed the import statement. Can't explain why, but that seems to be the reason.

@fipro78 now all test succeed... can you maybe give some manual instructions and where /when you would it expect to fail with the given example? I'll then take a look at it.

I followed my tutorial after I updated to the automatic manifest generation. And everytime I change the version back and forth the issue appears.
