Change Order Of The name Argument To Match Numpyro

[AFg6K7h4fhy2]

As per DHM:

name should be the first argument to the constructor of all RandomVariables, and should be mandatory.

This makes RandomVariable constructors follow the same pattern as calls to numpyro.sample(), which have the name first. This is relevant because the name attribute of a RandomVariable is used to construct site names for any numpyro.sample or numpyro.deterministic calls that occur within the RandomVariable's sample() method.

Currently, some RandomVariables have name as the first constructor argument, but others do not, and some have default values for name (which #306 should fix)
