Pass id rather than object as the 5th argument to h5d_read

[grero]

This should fix issue #140.

[bjarthur]

while this fixes the first error when i do ]test MAT locally, it doesn't fix the next one:

ERROR: Package MAT errored during testing

i'm on master of both MAT and HDF5. strange that travis reports no errors. tests pass locally for you?

[jmert]

CI failures are solved by #142.

[musm]

Does this need to also go in 0.8.1 ?

[jmert]

To avoid the deprecation warnings completely, yes, it should go in the next release. Thanks!
