test: fix import and access e2e tests due to recent changes (#4467)

This should fix `import` and `access` Cypress e2e tests after recent
changes were introduced:

- `import.spec.ts` - Expected '50%' to be contained in the page, however
now [we are lazy loading the accordion
content](https://github.com/Unleash/unleash/pull/4454);
- `access.spec.ts` - Expected 'within a project are allowed' to be
visible as a role description, however [we updated the predefined roles
descriptions](https://github.com/Unleash/unleash/pull/4451);
