hooks: print out more information when loading a python hook fails

When loading a python hook with file syntax fails, there is no
information that this happened while loading a hook. When the python
file does not exist even the file name is not printed. (Only that a
file is missing.)

This patch adds this information and a test for loading a non existing file and
a directory not being a python module.
