Scroll correctly when cursorPosition is changed within onTextChanged.

Emit textChanged() before adjusting size and scroll positions otherwise
the calculations will be based on the cursor position before it's moved
in handler and because the cursor position won't ultimately have changed
there won't be a follow up cursorPositionChanged() signal to trigger a
second set of calculation.
