This LPS happens in PortalImpl.java, different from LPS-92844

All layouts are gotten from database or cache even when only a few of them will be shown. This behavior was detected after user login, when layout tree is rendered.

Master: PortalImpl.java#L1106-L1112 
7.1.x: PortalImpl.java#L1108-L1114 
7.0.x: PortalImpl.java#L1079-L1085#L335-L337 

To reproduce it, since when rendering a layout, all layouts are retrieved also in com.liferay.portal.events.ServicePreAction._initThemeDisplay(HttpServletRequest, HttpServletResponse) the script provided in the comments can be used to check if after the method is fixed the layouts are cached after PortalImpl.getActualLayoutQueryStringComposite gets called.
