Prepare rename breaks if you have edited the symbol just before the call.

[yyoncho]

First, I started getting this error when using Extract Field refactoring. Apparently, Emacs is much faster than vscode for the rename call which causes the prepare rename failure.

Then I was able to reproduce it manually in vscode by pressing very fast Backspace + F2 when the cursor is placed on a field. Note that you might need a bit more complex project to trigger the behaviour(I was using one generated from spring initializr, I can provide one but it should be relatively easy to reproduce the issue).

@yyoncho could you test https://github.com/snjeza/vscode-test/raw/master/java-0.64.0.vsix

@snjeza I tried that build and it seems to be working fine.
