LPS-44724 Update tests

hey @rotty3000, 

I've found the reason why we were breaking some test.

With this new logic we are creating the Resource when needed and it is created as SCOPE_INDIVIDUAL (as it was done before in other portal places - when adding DL portlet to page, i.e).

On the other hand, test logic is adding some resource permissions for SCOPE_GROUP and deleting them, BUT it's not deleting the permissions for the SCOPE_INDIVIDUAL, so the Assert  fails.

I've updated the tests by deleting this permissions too and seems to work fine.

Anyway, I haven't got enough knowledge about the permission fw to know if I am missing something or it this could have any collateral implication.

Do you think update the test is the right solution or could it be a problem in our permission fw?

Thanks!!!!
