restore: invalidate cache-tree when removing entries with --staged
When "git restore --staged <path>" removes a path that's in the index,
it marks the entry with CE_REMOVE, but we don't do anything to
invalidate the cache-tree. In the non-staged case, we end up in
checkout_worktree(), which calls remove_marked_cache_entries(). That
actually drops the entries from the index, as well as invalidating the
cache-tree and untracked-cache.
But with --staged, we never call checkout_worktree(), and the CE_REMOVE
entries remain. Interestingly, they are dropped when we write out the
index, but that means the resulting index is inconsistent: its
cache-tree will not match the actual entries, and running "git commit"
immediately after will create the wrong tree.
We can solve this by calling remove_marked_cache_entries() ourselves
before writing out the index. Note that we can't just hoist it out of
checkout_worktree(); that function needs to iterate over the CE_REMOVE
entries (to drop their matching worktree files) before removing them.
One curiosity about the test: without this patch, it actually triggers a
BUG() when running git-restore:
BUG: cache-tree.c:810: new1 with flags 0x4420000 should not be in cache-tree
But in the original problem report, which used a similar recipe,
git-restore actually creates the bogus index (and the commit is created
with the wrong tree). I'm not sure why the test here behaves differently
than my out-of-suite reproduction, but what's here should catch either
symptom (and the fix corrects both cases).
