Alex Kavanagh 0353df7e28 Remove redundant path change and fix relative path change
Although this charm is rooted in 'hooks' (which is probably an error),
the actions were still using relative to root sys.path changes.  This
makes them absolute, which helps to tidy the path.  The charm should be
change to be rooted in the charm dir, and that requires more significant
changes to the unit tests.
