fix(ExpandableSearch): compose prop handlers with internal (#12135)

• fix(ExpandableSearch): compose prop handlers with internal

Closes #12135

The ExpandableSearch component passes a few callbacks from the underlying Search component in order to control its own state.

• onBlur
• onChange
• onExpand
• onFocus

These are not composed with any props on the ExpandableSearch component, meaning that any of those props specified will have no effect.

This fixes the issue.

Changelog

• ExpandableSearch: compose event callbacks with internal handlers

Testing / Reviewing

Hey @gi, thanks for the contribution and adding all the tests! I'm running into an issue where it seems like the ExpandableSearch no longer opens on click. Are you seeing this same behavior?

[gi]

@tw15egan Thanks for catching that. The composeEventHandlers function was throwing an error because no event was being passed to the onExpand call in Search. This is fixed now.
