[BUG] stepsNavigation allows you jump past steps that need validation

[newbreedofgeek]

Describe the bug
There has been some regression after last few PRs, you can now directly jump past steps that need validation (when you use the top navigation links via stepsNavigation)

To Reproduce
Steps to reproduce the behavior:

1. Run the Dev server or go to live demo https://newbreedofgeek.github.io/react-stepzilla/
2. Click on 'step 6'
3. It goes directly to Step 6, even though Step 3 had a validation condition

Expected behavior
When we clicked on 'step 6' it should do nothing as it detects a middle step needs validation. The behaviour should be the same as follows.

1. Run the Dev server or go to live demo https://newbreedofgeek.github.io/react-stepzilla/
2. Click on 'step 6'
3. It goes directly to Step 6, even though Step 3 had a validation condition
4. now click on 'step 3'
5. now click on 'step 4' - notice the validation is shows
6. now click on 'step 1', now try to jump to 'step 6' again. Notice that it now prevents you and does nothing. Seems this direct jump logic is trigger only after we did 5. above
