I've moved all the logic relevant to WBIO into a single file in order to
be able to replace it.
I have tried to upgrade WDIO in order to use the latest version and it
got stuck on my computer.
Furthermore, I was not able to run it locally which made this whole
cycle very long.
After this will be merged I will replace WDIO with cypress.
This doesn't change anything, only moves some code in the tests to a
single file, removes unneeded files and uses the driver pattern, which
will later allow switching the underline WDIO with Cypress.
