Code presenter: fix subscription to interaction model changed

[tinchodias]

Code presenter breaks the general presenter-adapter spec2 pattern when it subscribes itself via whenInteractionModelChangedDo:. Normally, the Morphic adapter subscribe on their buildWidget.

Spec/src/Spec2-Code/SpCodePresenter.class.st

Lines 653 to 658 in b4d3215

	SpCodePresenter >> registerEventsForStyling [
	self whenInteractionModelChangedDo: [ :im |
	self withAdapterDo: [ :anAdapter |
	anAdapter interactionModel: im ] ]
	]

Same happens in other properties of text presenter with selection: there is whenSelectionChangedDo: available, but when adapter is informed in this way:

updateSelectionFromModel: aSelection

	self withAdapterDo: [ :anAdapter | 
		anAdapter setSelectionFromModel: aSelection ]

But also others: look at senders of withAdapterDo:. So I may be wrong with this issue.
