command: Partially fix TestMetaBackend_planLocalStatePath 

This test is testing some strange implementation details of the old
local backend which do not hold with the new filesystem state manager.
Specifically, it was expecting state to be read from the stateOutPath
rather than the statePath, which makes no sense here because the backend
is configured to read from the default terraform.tfstate file (which does
not exist.)

There is another problem with this test which will be addressed in a
subsequent commit.
