Upgrade/Install: Initialize plugin dependencies during ajax plugin search.

This ensures that a plugin's "Deactivate" link is disabled for dependency plugins during searches when a dependent plugin is active. It also ensures the "Requires" metadata is shown for dependent plugins, and the "Required by" metadata is shown for dependency plugins.
