This CL fixes two bugs in SampleSpellChecker that prevented the sample
spell checker from working in an actual TextView.
1. The order of constructor arguments for SentenceSuggestionsInfo() was
wrong.
2. SuggestionsInfo always needs cookie and sequence attributes from
TextInfo.
Test: manual(Enable the spell checker from Android settings and type
in a TextView)
Bug: None
