monaco_editor: don't use automaticLayout for now

In monaco 0.20.0 "peek references" is not properly displayed when
automaticLayout is true. This is fixed on master branch so next release
should be OK.

For now, use a resize event handler to re-layout the editor when size
change, then we don't need the automaticLayout.
