Fix didExceedMaxLines test fails on API 21

This bug reproduce in a corner case:
1. when ellipsis width is very small and only allow 1 char to be displayed.
2. ellipsis is turned on.
StaticLayout may not apply ellipsis because that will remove all content.
To fix the issue, we no longer assume that StaticLayout will always ellipsize exceeding text when ellipsis is turned on.
