Git stash pop behaviour with

[jdmerinor]

Reproduction steps

• In branch A with master as remove we have a new file untracked.
• In master we have added the same file already and it's part of commit a123

we are updating branch A to the commit a123 so we are doing:

var stash = repository.Stashes.Add(signature, StashModifiers.IncludeUntracked);
repository.Merge('a123', signature);

if (stash != null)
{
	repository.Stashes.Pop(0);
}

if(repository.Index.Conflicts.Any()){
      showUserAllTheConflictsAndGiveOptionsToFixThem
}

Expected behavior

When doing the Pop the change should get marked as having a conflict and being modified

Actual behavior

There won't be any conflicts even though the file is marked as modified and has been modified with the conflict markers
