Take ble-file-transfer-js 1.1.0 and drop the local read guard

1.1.0 rejects readFile()/listDir() when the link is down or drops mid-request:
checkConnection() rethrows, and the response promise is installed before the
request is written. That is what the _whileConnected() wrapper existed to do,
so it goes.
