Attempting to undelete a redacted node produces a NPE in undelete plugin

[rickmastfan67]

Steps to reproduce:

1. Have the undelete plugin installed.
2. Attempt to undelete the following node: 334515920

What should happen:
JOSM should tell you that the node was redacted and can't be undeleted.

What happens:
JOSM attempts to undelete the node, but has an NPE show up (only seen in the console).
