[FL-1104] Fix NFC crash and missing NfcMessageTypeDeviceNotFound event (#400)
* Remove asserts from platformProtectST25RComm, fix issue with concurrent access.
* NFC Worker: fix bug in nfc_worker_poll causing worker to skip sending ofNfcMessageTypeDeviceNotFound event
* Fix python linter: stick to old beta
