Fixed test case failure because of wrong dyn version.

- Replaced old dyn by creating new in 0.6.3. Original dyn file was having error and was not able to open in 0.6.3 and in 0.7.1 it was throwing dummy node error.
- New dyn correctly opening in 0.6.3 and getting migrated to 0.7.1 without having any dummy node.
- Test case is no passing but it will still need more verification, which I will be adding while revisiting test cases.
Updated dyn to have 0.6.3 version instead of 0.7.0 version
