Fixing line truncation issue when numberOfLines = {1}

Summary:
Changelog:
[Android][Fixed] - Fixing line truncation issue in Text containing /n when numberOfLines = {1}

When the text has multiple lines (with new line characters \n to hard-break the lines), and the first line is short enough to fit, Text component with `numberOfLines = {1}` doesn't display "..." at the end and rather disrespects the /n character.

With `numberOfLines = {1}`, On iOS it translates to
`line 1`, on Android & Web it translates to `line 1 line 2...`

**Expected Behavior :**

`line 1...`
