bug 1170153 - check documents have a docshell before trying to tell the parent process about new remote DocAccessibles r=davidb

Browse Source 
We should never create DocAccessibles for documents that are going away so it
seems like this shouldn't be necessary, but without a test case its hard to
know why we are creating DocAccessibles for documents without docshells.  So
for now work around the issue and hope it doesn't matter in practice.
