Use un-aliased node paths on search controller

Problem/Motivation

The SearchController generates a result set with static hrefs and data attributes that aren't used to dynamically update the hrefs attributes if the targeted node's path changes.

This is being addressed on #3213528: Integrate Linkit through the integration with Linkit module, but the Gutenberg module should provide a solution when Linkit module is not in use.

Proposed resolution

Use the un-aliased node path to prevent the link from breaking when the targeted node's path changes.
