Matthias Clasen 5398a160ad Add a test for entry signals
These tests check that text and selection boundaries are in a
consistent state when we emit notifications, that ::insert-text
and ::delete-text are emitted before any changes, and that
::changed is emitted after property notifications when inserting
or deleting text.
