TextInput multiline text does not appear centered if only one line

### Current behaviour
When TextInput has `multiline` prop, the text is vertically aligned towards the top if the input field contains only one line (screenshot 1). If the text is longer and shows two or more lines, then everything appears fine and the content is centered accordingly. (screenshot 2). You can see from the image below where i marked the spacings in red

### Expected behaviour
Text Should be centered inside the the TextInput even if it contains text which takes up only a single line.

Start by reproducing the supplied multiline TextInput example on iOS and Android, then trace the TextInput implementation and its multiline layout behavior. Confirm the result against the screenshots and verify that one-line content is centered without regressing two-or-more-line content.
