Copy vendor map before composer install

[TNAJanssen]

If you link the vendor folder and your build fails and you go back, you will be hanging with wrong versions of your packages.

So a different solution would be copying the vendor map to the new release to speed up composer install.

Any thoughts on this?

I would never link the vendor file for this reason alone.

But copying the current vendor to the new release folder sounds indeed like a nice speed up.
