Fix backForwardGoToItemShared connection
https://bugs.webkit.org/show_bug.cgi?id=324451
rdar://187692326
Reviewed by Richard Robinson.
BackForwardGoToItem can arrive at ProvisionalPageProxy, on the provisional
process's connection, but the check was marked against
legacyMainFrameProcess(). Marking a connection that is not the one dispatching
sets m_didReceiveInvalidMessage outside Connection::dispatchMessage's
save/restore of it, so didReceiveInvalidMessage() never runs and the sender is
not terminated. It also asserts in debug builds.
Pass the sending connection down instead. connectionForProcess() existed only
for the old workaround, so it goes too.
