test: Add fixtures for missing findings

[codeworrior]

Missing findings:

• a renderer definition that re-uses the render function from another renderer
  • a similar case is solved via https://github.com/SAP/ui5-linter/pull/440
• ~~a missing manifest:"json" entry in a component~~
  • solved via https://github.com/SAP/ui5-linter/pull/428
• ~~the use of a deprecated setting in a constructor call (the same setting is found in a different context)~~
  • solved via https://github.com/SAP/ui5-linter/pull/437
