When we run make generate-po, generated .po files might contain strings marked as fuzzy or obsolete. Those strings are not supposed to be found in Tuleap codebase (which is not the case currently).

For a first step, I suggest to facilitate developer work by removing automatically obsolete strings (they don't have to manually do the purge) and by emptying fuzzy strings.

If we see that it is not enough we can later create a hook, or/and a CI job do check that no fuzzy nor obsolete strings are contributed.
