Fixed PHP autosuggest placeholder is not being used.

[fabianmarz]

Description of the Change

• While the autosuggest search string placeholder value can be changed via a PHP hook, it's not picked up by the autosuggest JS and therefore the query will break or doesn't deliver the correct results.

Alternate Designs

• Instead of deleting const placeholder = 'ep_autosuggest_placeholder'; I considered using const placeholder = queryJSON.placeholder; but decided to drop the line completely as the placeholder is used in buildSearchQuery() only.

Benefits

• Don't break any the results if other than the default value is used :)

Possible Drawbacks

• X

Verification Process

• Inspected the query after the search and replace was done to ensure the query runs with the actual search term.

Changelog Entry

Fixed - Autosuggest doesn't work if the placeholder is changed via a ep_autosuggest_query_placeholder filter.
