Bug 1030993 - Fix assertion failure in reftest css-ruby/ruby-whitespace-1.html. r=dbaron

Browse Source 
Fixes the assertion failure with text:
"###!!! ASSERTION: Wrong line container
hint: '!aForFrame || (aLineContainer == FindLineContainer(aForFrame) ||
aLineContainer->GetType() == nsGkAtoms::rubyTextContainerFrame ||
(aLineContainer->GetType() == nsGkAtoms::letterFrame &&
aLineContainer->IsFloating()))', file
/home/sgbowen/builds/mozilla-central/layout/generic/nsTextFrame.cpp, line 1259"
which occasionally appears when opening pages with ruby or when running ruby
reftests.

Updates the manifest for ruby reftests to the current expectations (adjust
assertion counts, etc.)
