Removed dependency on dbms_utility.name_resolve.

Fixed issue with utPLSQL failing to run when schema contains package named the same as schema owning it.
It is now possible to have utPLSQL test package like this:
```
create or replace package some_schema.some_schema as
  --%suite

  --%test
  procedure sample_test;
end;
/

create or replace package body some_schema.some_schema as
   procedure sample_test is begin ut.expect(1).to_equal(1); end;
end;
/
```

The tests from the package can be invoked by calling:
`exec ut.run('some_schema.some_schema');`

If only schema is provided, all test packages in schema are executed.
`exec ut.run('some_schema');`

Resolves #569
Resolves #885
