LocalConnectivity.h5 in the DefaultProject has duplicate Surface GUID ref

The effect in web import is that sometimes (not all the time), this error appears:

Could not set 'surface' field on 'LocalConnectivity' because there is no 'CorticalSurfaceData' with gid: 3d4a1514-47ca-11e4-99ec-3c075431bf56 in database.

The problem seems to be with the LocalConnectivity H5 file distributed as part of the new Default_Project.zip, as it has 2 attributes in the root metadata:

• Surface (with the correct link towards an existing CorticalSurface in this project) and
• TVB_Surface (with an old GUID as value)

For compatibility reasons, we are still reading the "surface" tag, but it is not reliable which of the two tags gets used; this is why at times it works and other times not.
