Changed the minimum count of dummy data (folders and notes)

Fix #1562

At least two dummy folders/notes are required for reordering folders and moving notes in the test. Current dummy data implementation might result in generate only one folder / note.

Please see code below.

TestDummy.js

var folderCount = Math.floor((Math.random() * 5)) + 1
/* ... */
var noteCount = Math.floor((Math.random() * 15)) + 1

However, following tests access to the second item in the folders/notes array.

reorderFolder-test.js

  const secondFolderKey = t.context.storage.json.folders[1].key

moveNote-test.js

  const note2 = t.context.storage1.notes[1]

Increased the minimum count to 2 resolve the issue.

Wow, I didn't notice there are usages of Math.random. I think this is a bad practice when testing. We should pull out them somewhen.

Anyway, great work!
