Merge pull request #1220 from gem/refactor-sites

Remove site_collection column from the database
qa_tests/risk:

Removed base class `test` methods so that nosetests doesn't get
confused when collecting tests. The presence of the base class
methods was causing risk qa tests to be included in nosetests'
test collection when `nosetests -a '!qa'` was explicitly used.

export/hazard:

Fixed the retrieval of `hazard_curve_multi` metadata. IML/IMT
information wasn't being collected from the correct `Output`.
tests/export/hazard_test:

Do XML validation for `hazard_curve_multi` outputs as well.

Previously, all artifacts except for this type were being validated.
export/risk:

Corrected `quantile_value` handling in `export_loss_fraction_xml`.
