In text fields, fixes #cancelSafely (i.e. CMD+L) for models that directly derive their textual contents user input (i.e. #textEdited:) without an extra #accept step. Examples include all uses of PluggableTextSpec >> #editText: such as Inspector, ObjectExplorer, and SearchBar. And the Debugger, which uses Inspector.

+ 	"Cancel all edits by replacing the content with the original contents. Retain the undo history. If a model is listening to #textEdited and maybe also directly derives #getText from it, clear the edit buffer first, so that a cancel means deleting everything."
