Cleaning test folder

[nicola]

• The test folder should be cleaned, meaning that all of its files that are not .js should be in a folder resources and testfiles should be a subdirectory of resources (it is important for testing to have a subdir!), possibly called testContainer. (done Moving test folders #80)
• Splitting the test.js and restructure tests (done Improving test structure #85)
• Also, there are files that are not needed.

This will be part of the solid-tests cleaning effort
