Add more automount tests

This adds tests for the automountlocation_tofiles and
automountlocation_import commands, and to automountmap_add_indirect
with the --parentmap option.

The tofiles test checks not only the XML-RPC output, but also the
output_for_cli method.

The import tests load data from tofiles output to the directory
and check that tofiles output matches.
This only works when all maps are connected to auto.master.

Two minor touches to the automount plugin itself: remove an extra
space, and don't hide the traceback when re-raising an exception.
