Generally, when starting a new branch packages are not copied over to avoid wasting disk space. So, old packages will be still pulled in from old branch directories (under packages/). This commit adds a function that automatically flush back old-branch packages into the current one. Let's say we have just bumped our repo from branch 1 to branch 2. We have 3 packages into it that are still placed inside /packages/1. Everything works until we decide to drop support from branch 1, in this case, we would have to rebuild all these packages wasting a lot of time. With "flushback" this is done automatically without touching packages integrity.
