Related minor issue: by not clearing the error string of the thread a
successful download after a failed download would still show an error message.
Trivial patch attached. Not exactly sure where to put the error.clear()

The error string of the download-from-divecomputer thread was not
cleared. Thus, if an error occured an error message was also shown
on subsequent successful downloads.
