amend: moving first assignment of newid closer to its use

newid was needlessly further away from where its intended to be used
leading to bad readability. This commit moves it to address the same. The end
goal is to remove the redundant commit in the amend code path and this commit
takes care of cleaning up some unrelated code before that change.

Test Plan:
ran the test suite

Differential Revision: https://phab.mercurial-scm.org/D597

In the merge below, the file "foo" has the same contents in both
parents, but if we look at the file-level history, we'll notice that
the version in p1 is an ancestor of the version in p2. This test makes
sure that we'll use the version from p2 in the manifest of the merge
revision.
