Use ✅ instead of ✔️ for better cross platform look

You currently use:

export const Icon = {
  skip: '✖️', // ':heavy_multiplication_x:'
  success: '✔️', // ':heavy_check_mark:'
  fail: '❌' // ':x:'
}

This is how it looks on Mac:

I suggest using:

export const Icon = {
  skip: '✖️', // ':heavy_multiplication_x:'
  success: '✅', // ':white_check_mark:'
  fail: '❌' // ':x:'
}

... the skipped test is also probably better represented with the ⚪ emoticon. It evokes emptiness, just like looking at the empty summer sky over Tatras...
