fix(pat auto suggest): Fix issue with pat-auto-submit.

Also dispatch a input event after a value has changed to let auto-submit do a form submit.
This fixes an issue introduced in Patternslib 7.0.0.
Note: this will be revisited when reworking auto-submit and input-change-events for standard JavaScript event compatibility.
