Fix: Ellipsis is wrongly applied or not applied in TextView.

In current implementation, ellipsis is applied after
coptuting line breaks without limiting line count. As a
result, ellipsis can be skipped or- wrongly applied because
the breaks are computed to fit with the width.
With this change, the last line and overflowed part are
treated as a single line when the number of breaks exceeds
the remaining line count.
