Distribute nodes and selected but already deleted nodes

[alv]

The title may seem cryptic, but steps to reproduce:

• draw a unclosed way with four nodes
• select each node
• distribute nodes
• select one of the middle nodes
• delete that node
• using the select history on the right hand selection panel, select the first line that reads "4 nodes"
• you see three remaining (as in not deleted) nodes selected
• select distribute nodes

expected result:

• equal distances between the three nodes

result:

• no change, equal distance between all four nodes, including the deleted.
