Can not get sourcetable from Lefebure NTRIP Client

[d1ken]

If I manually set mountpoint it is ok.
But if I select Data Stream - Refresh Stream List, there are exception:

(node:24180) UnhandledPromiseRejectionWarning: TypeError [ERR_INVALID_ARG_TYPE]: The "chunk" argument must be of type string or an instance of Buffer. Received an instance of Promise

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

Error only on V1Processor.
Easy fixed - just copy printSourcetable (with async-await) from V2Processor.
