Moves negative tests from test_multiple_create

This change set moves the negative tests in test_multiple_create to
a new file test_multiple_create_negative

Also removes usage of modules directly.

Note: HACKING.rst
The second requirement is that all negative tests must be added to a negative
test file. If such a file doesn't exist for the particular resource being
tested a new test file should be added
