Supress text replacement spans for ellipsis

When a sequence of characters belonging to a text is ellipsized, we
usually replace the first characters with ... and then all the others
with a 0 width character, knowing that they will be drawn, but will be
invisible. However, these positions could have had ReplacementSpans
attached to them, such as EmojiTypefaceSpan when the EmojiCompat library
is used. When this happened, all the ellipsized out characters were
invisible, apart from emojis, which were still drawn as usual (as they
were replacing sequences of 0 width characters).
This CL fixes this behaviour, by skipping those ReplacementSpans that
were completely included in ellipsis. Please check the bug for a more
detailed explanation.
