silxview: Refresh on a file open with subdataset is not working properly

[vallsv]

Silx view allow to open a sub dataset/group from a hdf5 file.

In this case only this subtree is displayed.

But when you click on refresh, the parent file is appended as a new source.

Probably the refresh is not properly working too.

To reproduce

• Open silx with an HDF5 with a sub path

• Select the source
• Click on the refresh button
