Fix textedit intrinsic size metric

[lucasmerlin]

Since textedit is doing the justify layout calculation itself, we need to report the original desired_size as intrinsic size, instead of the value passed to allocate_space.

I wonder though, is it still necessary that the TextEdit does the justify calculation itself instead of relying on the ui layout to do it? As far as I understand it, justify should be handled by the ui.allocate_space call.

I think ui.allocate_space should be able to handle it, unless I'm missing something. Could just be legacy.
