This fixes a case in which we forgot to assign flags to TextNodes created through AddBmpCharacters AddNonBmpSurrogatePairs AddLoneLeadSurrogates AddLoneTrailSurrogates functions. If these initially had a flag (e.g. case-insensitive 'i') set, that information was lost. This bug resulted in missing case folding in no_i18n builds (perhaps other things as well that just aren't covered by our test suite).
