Moving from Node editing to Select or Node Edit Tool

Follow the steps below:

1. create a closed shape with at least 3 nodes

2. select a node

3. break the node into two nodes

4. move one of the nodes away

5. join the two nodes

6. while nodes are still selected, select the 'edit
path nodes' tool

7. crash will result with following message

** ERROR **: file nodepath.c: line 2186
(sp_nodepath_node_destroy): assertion failed: (sp->last
== node)
aborting...
Aborted

NOTE: I hope that the previous bug I posted, # 856686
is related to this one.
