Turns out that supplying NULL to group_register in the
mca_base_var_group_component_register is not a good
idea if one wants for ompi_info to work as intended.
The ugni and vader btl's both call this before
registering component variables. This borks up
the ompi_info works since NULL is supplied as the project
name. So, now supply the project name rather than
just NULL to group register.
Fixes#4020.
