looper is forcing the pipeline file to be executable, even if the command template doesn't execute it (I was using 'python script.py').

Currently, in Looper's conductor.py, we check if the commands in the pl_iface is executable: https://github.com/pepkit/looper/blob/145c0d6796d45e45a4ec133beed5be30e1860553/looper/conductor.py#L724-L725

This was implemented as a potential solution to this: https://github.com/pepkit/looper/issues/195

Specifically, it is using: is_command_callable from ubiquerg

https://github.com/pepkit/ubiquerg/blob/bbca867a7c3581bad51723977db3791d999d8591/ubiquerg/system.py#L11-L30

This is totally unrelated to #195, actually. That's about the commands in a pipeline.

The problem is that this is referring to the pipeline script itself. These are two completely different things.

The original changes are now reverted.
