Fix transferFromDownloadsToMyFilesMove transfer.js test

The transferBetweenVolumes function adds the file to be moved into
the list of expected files after the move, only runs if the flag
"isMove" is false. Because of this, the file that was moved was not
added to the list of expected files, and the test can fail.

Removes this condition, and do not add the file to be moved to the
list when the source is the same as the destination, or if the test
is expected to fail.

All tests that use transferBetweenVolumes now pass in step-by-step
mode, to complete issue 1035220.
