Currently, utplsql, when invoked with unit test package name, will run all the tests for suitepath of that package.
If a package has child packages (by suitepath), those will also be executed.

When having such package, utPLSQL does not provide ways to run only that package.
We should change that behavior so that running test package by name should only invoke tests from that package.
If the package is part of suitepath, all the beforeall/afterall of parent packages should still be invoked.
No child packages should be called.
The behavior of package execution by suitepath should not change.
