Add .h5 in extension using the 'same' reference in scil_tractogram_commit

[gagnonanthony]

Quick description

Reference was set to 'same' only if the input tractogram was a .trk, which made the following saving function fail. Simply added the .h5 in the extension possibilities.

Does the .h5 have its own reference ? We commit omit one for TRKs as they include the ref's affine in their header. What about these .h5 ?

Also a duplicate of #1279 ?
