Fix updating multiline BottomBar

[dawidpawlowski]

When I try to update my BottomBar by using updateBottomBar method and new text has more lines than previous text, content in console is overwritten. I make small fix to resolve this problem.

Code snippet to reproduce the problem:

var BottomBar = require('../lib/ui/bottom-bar');

var ui = new BottomBar();

function startInterval() {
  var i = 0;

  var inter = setInterval(function () {
    i++;

    var table = 'line - 1\nline - 2\nline - 3\nline - 4\nline - 5\nProgress - ' + i + '%';

    ui.updateBottomBar(table);

    if (i % 20 === 0) {
      ui.writeLog('work...');
    }

    if (i === 100) {
      clearInterval(inter);

      ui.updateBottomBar('Installation done!\n');

      process.exit();
    }
  }, 50);
}

startInterval();

Result before fix:
