Add assets test suite (#400)

* Started POM and assets test

* FEAT: Adapt unit tests from RIGS to assets

* CHORE: pep8...

* Added Asset Create and Edit forms

* Add non-cable asset creation test

* CHORE: Frickin pep8...

* Add cable asset creation test

* Basic asset create validation testing

* Asset edit tests are here

A bit dodgy in places but par for the course for me :P

* Add access level tests

* Delete unused code

Much less effort way to increase coverage stats :D

* Add delete sample data test for completeness

Chasing that sweet 100% coverage...

* Add supplier list page + tests

Also fix the supplier page not being ordered alphabetically

* Helps if I add the migration...

* Add supplier create/edit tests

* Asset duplicate tests

Also fixed some random bugs

* Asset search tests

* 404 tests and test that everything requires authentication

* Test visibility of form errors

And fix supplier form not displaying errors correctly!

* Fix broken search test
