Fix stuck on loading screen on transaction details - Closes #565

[faival]

What was the problem?

clicking on a transactionRow of an account doesn't display it's details.

How did I fix it?

• Avoid usage of this.props on presentational components.
• nextStep should pass value from props.
• add integration tests

How to test it?

go to /explorer/accounts/5932438298200837883L, and click on a transaction row:

• detailView of that transaction must be displayed.
