tests: avoid referring to pvec in demandimport test
Nothing else currently uses pvec, so we may want to delete it (but
Augie Fackler says he may want to use it). To enable deletion, this
patch replaces it by the error module in the demandimport test (any
module works). However, since the error module had already been loaded
at this point in the test (via the util module), I moved it earlier in
the test so it's still not loaded (although I'm not sure if that's
even relevant to the test).
