Gracefully ignore bad remove-project line

Sometimes, we don't care if the remove project is referring to a
non-existing project and we can just ignore it.  This change allows us
to ignore remove-project entries if the project that they refer to
doesn't exist, making them effectively a no-op.

Because this change breaks existing configuration, we allow this to be
configuration controlled using the `optional` attribute in the
remove-project tag.
