Add Tests for `Preferences>Keybidings`
This commit adds tests that check that: 1) Default key binding accelerators are distinct. 2) Message dialog appears when a duplicate key binding accelerator is attempted to be assigned to a different action. 3) Duplicate key binding accelerator cannot refer to more than one action. Also, `active_message_dialog` attribute was added to `PrefsEditor`, so that tests could get a reference to a message dialog window.
