amend: don't remove unselected removals from memctx

When there are removed files in the working copy and they are not
selected to be amended into the parent, the `filectxfn` we create for
the `memctx` would still return `None` before this patch. That's
clearly incorrect; we should return the `filectx` from the unamended
commit. Somehow it seems to not matter much except for the case with
copies stored in changesets.

Thanks to Kyle Lippincott for doing all the debugging and identifying
the fix for this issue.

# This software may be used and distributed according to the terms of the

# This script can be used to bootstrap a Mercurial build environment on
# Windows.
#
# The script makes a lot of assumptions about how things should work.
# For example, the install location of Python is hardcoded to c:\hgdev\*.
#
# The script should be executed from a PowerShell with elevated privileges
# if you don't want to see a UAC prompt for various installers.
#
# The script is tested on Windows 10 and Windows Server 2019 (in EC2).
