api!: remove APIs to create protected chats

Create unprotected group in test_create_protected_grp_multidev
The test is renamed accordingly.

SystemMessage::ChatE2ee is added in encrypted groups
regardless of whether they are protected or not.
Previously new encrypted unprotected groups
had no message saying that messages are end-to-end encrypted
at all.
