Changing test default to use RHS as initial vector for Hybrid Gmres #4159

Description

There are random test failures for this test, #4159, and I can only speculate that it is happening because this test is using random vectors for both the RHS of the linear system and initial vector for computing the polynomial for polynomial-preconditioned Gmres.

Changing the default to just using one random vector for the linear system, which will then be used as the initial vector for computing the Gmres/Arnoldi polynomial.

Motivation and Context

Trying to stop the random failures from this test.

How Has This Been Tested?

OSX, GCC 7.2, Serial.
