Integrity checker should check Issue types when checking for invalid test runs

When checking for invalid test runs in the integrity checker, Xray is not validating the issue types. This allows that a Test Run can exist between wrong issue types, like for example between a Test Execution and a Story.

In this situation, an invalid Test Run will appear in the Test Run Summary gadget.

How to reproduce:

• Create a new Test and execute it in a new Test Execution
• Disable Xray
• Change the Test issue type to another (ex: to a Story)
• Enable Xray
• go to the Test Run Summary gadget and introduce a filter that only contains the Test Execution, the migrated issue will appear when it shouldn't
