3461 duplicated script names

[hiker]

Fixes #3461.

[hiker]

I've fixed the unit test failures by slightly changing the test (instead of setting sys.path, I chdir into the script directory).

We do get additional failure in example, since without modifying sys.path, helper scripts in the same directory as the psyclone scripts are NOT found anymore (unless you set PYTHONPATH=.). We could still modify sys.path in generator.py to accommodate that use case, I have started the CI to see if nemo/lfric relies on this.

Failures in one example and nemo (lfric is fine) indicate that we should modify sys.path when importing and executing a script (so that helper scripts in the same directory as the script are found). That was done in ab86dd3, so once I've updated the documentation this should be ready to go.
