Thanks a lot, @heplesser, for this fast fix. All three functions nest.random.normal(), nest.random.lognormal() and nest.random.exponential() behave as expected now.

This PR aligns the non-spatial normal, lognormal and exponential parameters in NEST by allowing
std == 0orbeta == 0, respectively. For the exponential parameter, a test against negative beta is introduced.This PR only modifies the plain random parameters. For spatial random parameters, we still require that parameters are strictly positive.
This fixes #3736.
