Repro steps

• Put the matGoogleMapsAutocomplete directive on an input within a form element
• Bind an ngSubmit event to the form and console.log when it's triggered
• Start typing an address into the field with the autocomplete directive, DownArrow to an option, and press Enter.
• The ngSubmit event gets called.

Desired functionality

Allow more control over events triggered by the Google Maps feature so we don't have errant events triggered without knowing about them.
