Overlay bug fixes (#479)

Per this PR: yext/answers#1168, the hook "onSubmit" was renamed to "onConductSearch". There was also a bug that was always using the button's max-width (100%) rather than the default button width when no text was present.

TEST=manual

Test locally using a newly generated HH test site with the theme and v1.7 of the Answers SDK. Serve, conduct search via buttons and via autocomplete.
