Subject: [PATCH 2/3] In t7519, populate untracked cache before test

From: Tao Klerks <[email-masked]>

In its current state, the t7519 test dealing with untracked
cache assumes that
"git update-index --untracked-cache" will *populate*
the untracked cache. This is not correct - it will only add
an empty untracked cache structure to the index.

If we're going to compare two git status runs with
something interesting happening in-between, we
need to ensure that the index is in a stable/steady
state *before* that first run.

We achieve this by adding another prior "git status"
run.

At this stage this change does nothing, because there
is a bug, addressed in the next patch. whereby once
the empty untracked cache structure is added by the
update-index invocation, the untracked cache gets
updated in every subsequent "git status" call, but the
index with these updates does not get written down.

That bug actually invalidates this entire test case -
but we're fixing that next.
