[ Tests ] Cypress: element is detached from the DOM error #1046

This is reported in cypress repo cypress-io/cypress#5743

Started to appear after we upgraded to Cypress 3.7.0. Appears only on local test run, does not affect CI.

This is a common error covered by Cypress documentation, https://docs.cypress.io/guides/references/error-messages.html#cy-failed-because-the-element-you-are-chaining-off-of-has-become-detached-or-removed-from-the-dom
but I believe that we are not the case mentioned there. We use cy.get().click() directly one after another.

TODO:

test if rollback to 3.4 version helps
~~test if update to 3.8.1 (latest) helps~~ does not help

New modals logic do not require hiding "exit" button from onboarding if device is not ready to work with. It also somewhat mitigates #1046 Seems like if there are less renders, the chance it happens is smaller.

* onboarding exit button always visible New modals logic do not require hiding "exit" button from onboarding if device is not ready to work with. It also somewhat mitigates #1046 Seems like if there are less renders, the chance it happens is smaller. * less unit test-like approach acting like unit writing unit tests is considered antipattern, see here https://docs.cypress.io/guides/references/best-practices.html#Creating-%E2%80%9Ctiny%E2%80%9D-tests-with-a-single-assertion other way round it gives us performance boost * clean up onboarding tests
