Crash on range invalidation
Crash on range invalidation, like reported by @waqar, I got it now today, too a lot ;=)
I think I have a fix, the issue happens when e.g. a one line range will enter invalid due to textremoved...
That was broken since EVER.
Perhaps somebody could try to add a unit test, I will just commit a fix to be able to work here with the master version.
The massive amount of ranges added by LSP helps to trigger this easily :P
