Polkadot update v0.9.42

[OverOrion]

See the following substrate PRs for details:

• https://github.com/paritytech/substrate/pull/13535
• https://github.com/paritytech/substrate/pull/13475
• https://github.com/paritytech/substrate/pull/13798

For the last one I opted for suppressing the warning, but will open an issue for benchmarking it.

Closes https://github.com/integritee-network/pallets/issues/172

Did the required followup changes, but now there is an internal substrate error: `Self::mutate_account``` will fail withNoProviders`.

The error originates from inc_consumers, where the providers field shoul not be 0.

Currently investigating why this happened.
