File not found error when saving a service with audio files

[Raoul Snyman]

When saving a service file that has songs with audio files attached, which has previously been saved, the following traceback occurs:

Traceback (most recent call last):
  File "D:\OpenLP_Code\trunk\build\pyi.win32\OpenLP\outPYZ1.pyz/openlp.core.ui.servicemanager", line 557, in saveFile
  File "D:\OpenLP_Code\trunk\build\pyi.win32\OpenLP\outPYZ1.pyz/zipfile", line 1007, in write
WindowsError: [Error 3] The system cannot find the path specified:
u"audio\\3abd9db4-e41b-11e0-b2f6-1c6f65b804c5\\05-It's all in your hands.mp3"

[Raoul Snyman (raoul-snyman)]

To reproduce:

1. Create a new service
2. Add a song that has an audio file or files linked
3. Save that service
4. Close the service (either via "new" or closing OpenLP)
5. Re-open the service
6. Add another item or items to it.
7. Save it again

superfly,

The test branch fixed the bug.

However, I linked an MP3 to a song and it doesn't play (either to preview or live). The mp3 plays fine from Media Manager/Media

Attached is the mp3

Did some machine cleanup, rebooted and retried OpenLP with mp3 attached to song. Worked fine.
