Remove tests not in bronze scope

[andheroe]

@camuel pointed out that those tests are not a part of Bronze Scope
I double check in http://95.217.182.99:3333/public/dashboard/a1b7a753-cab7-417a-b2c8-bc6d26967616?tab=8-function&object_type=function&project_type=&project_name=&category=&page_name=&fucntion=&file= and didn't find them, so this is confirmed.

I've also removed tests for update and delete DML based on @rampage644 suggestion.
