git-p4: add failing test for shelved CL update involving move/copy

Updating a shelved P4 changelist where one or more files have
been moved or copied does not work. Add a test for this.

The problem is that P4 requires a complete list of the files being
changed, and move/copy only includes the _source_ in the case of
updating a shelved changelist. This results in errors from Perforce
such as:

  //depot/src - needs tofile //depot/dst
  Submit aborted -- fix problems then use 'p4 submit -c 1234'
