Attachment: Bug 1617083 - Fix race condition with memory pressure events.

If a memory pressure event arrives after a new scene has
been published that writes persistent targets (i.e. cached
render tasks to the texture cache, or picture cache tiles)
but before the next update/render loop, those targets
will not be updated due to the active_documents list being
cleared at the end of this message. To work around that,
if any of the existing documents have not rendered yet, and
have picture/texture cache targets, force a render so that
those targets are updated.
