Tagged with `@mayfail` some scenarios that seem to be unstable / broken on CI and also locally.
`The user can backup seed phrase` scenario has been disabled due to its instability. It fails sometimes in the CI so it needs a review.
- Created new test case `tst_signUpAndQuit`. - Renamed `tst_settingsMenu` to `tst_mainSettingsSection`. - Created specific `bdd_hooks.py` for test case `tst_mainSettingsSection` and `tst_userIdentity`. Closes #8011
