Removed Failure category as most of them are now passing.

<h4>Summary</h4>
Earlier there so many failures in TestMigrationFramework project and we marked this entire test project as Failure. Now After fixing few things in this project almost 98% test cases are passing. few of them are failing but this PR will take care of those failing as test as well (except below mentioned two test cases.). Once this PR merge, there will be only two failures which will be taken care in next PR.

<h4>Solution</h4>
* Removed Failure category.
* Removed Nodes from few dyn file which has already been removed from the repo.

Test Files delete.dyn and ProjectPointOnCurve_3041.dyn are failing right now because of wrong migration of "Project Point on Curve", but I will be submitting another PR to take care of that.
