Fixed a crash in sync uploads
Fixed a crash in sync uploads

If a LocalNode is moved after it has been added to the transfer queue,
but before the transfer has been dispatched, the inicialization was
skipped and Cryptopp crashes due to an uninitialized encryption key.
This fix updates the path of the transfer only if it has been already
initialized.
