fix bug where some lines were not scrolling horizontally properly. The issue was that, when encountering a line break in 'skipToFirstVisualColumn' function, we should have recursively called the 'skipToFirstVisualColumn' function instead of the 'build' function. The reason is that our current column after a line break is 0, but we don't know if the start column to display is necessarily 0 in all cases.

fix bugs in implementing and using text buffer. Some functions did not save the drawMsg to the app's state, which we means we didn't draw in those cases. The text builder functions also drew cursors on characters even when the cursor is not at this position. Both of these bugs are fixed.
