Webservices tests need to be fixed up / made more robust

[Robert Lyon]

It expects web service enabled, default institution auth though web services set up etc.

will be good to get these tests sorted out asap as it will make other work/changes run smoother

I was trying to do some fixes and improvements around phpunit and realised that web services tests are quite broken. You can try it out by running tests with https://reviews.mahara.org/#/c/4042/ checked out. Rather than setting up data required for tests, websevices tests expect everything to be set up globally which I don't think is a correct approach. My opinion is that it needs to be fixed if we want unit tests to ever pass :)
