3.39 breaks copying between libraries using the GUI

[Amanda]

It seems that the new addition of copying between libraries using the content server broke the feature inside the GUI.

I'm on Linux, Pop!_OS 18.10 (Ubuntu 18.10 dirivitive)

Here's the error:

calibre, version 3.39.0
ERROR: Failed to copy books: Could not copy any books, click "Show Details" for more information.

Failed to copy a book, see below for details

Copying: <Redacted> failed, with error:

I see the identical error under MacOS 10.14.2, though in fact the copied file does appear in the destination library.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
