Unexpected deletion when replacing a draft tiddler

[Skeeve]

Try this with 5.0.7:
a) Create a tiddler "first version" with some text
b) Open it for editing
c) Change the name to "first version 1" BUT DO NOT SAVE
d) Create a new tiddler with some text and
e) give it the name "first version"
f) In the popup confirm that you want to overwrite
g) Note that the new "first version" is there
h) Save "first version 1"
i) Note that "first version" is now gone

Oh .... cool, it needed only 400 issues to pop up :)
I think this is related to #44 and may be #45.

Ha! @pmario gets the prize.

I think I can see a way that this could be fixed. When the tiddler is being edited in (c) it has a prospective title of "first version". Saving the second tiddler at (f) overwrites that prospective tiddler. Saving the original tiddler at (h) deletes the original prospective tiddler in the process of handling the rename.

The draft tiddler needs to keep track of the changecount associated with the original prospective tiddler. It could then only delete the prospective tiddler if it has not been modified since the draft was created.
