Fix flaky tests

[zeina-idris]

• Fixed most of the obvious flaky tests by adding { timeout } to most buttons that call to the backend
• CreateCusomer() and Login() are now in different commands in commands.js

• 160 Handled "isLoading" case in:

  • Cart
  • Order list
  • Product list
  • Added graphqlTimeout option in cypress.json configuration.

ProductList component was failing in the unit test, because it's expecting products! So I start the component with v-if=products then we have all the cases in this order: v-if=isLoading v-else-if=products.results.length v-else bad case Tested it everywhere and works like a charm.
