After upgrading from 1.625.3 the parameters defined in the abstract project no longer works.

Steps to reproduce:-

1.  Create an inheritance project. Set a inheritable parameter with name "parameter1" and value "if you see this then it is working"
2. Add an execute shell and write "echo ${parameter1}"
3. Mark the project as "is abstract project"
4. Save the project with name "BASE-execution"
5. Create another inheritance project and name it "Main-Project" . Set parent project as "BASE-execution".
6. Save the project and execute "Main-Project" . Check the console output. blank echo will be displayed.
