Catch GetSubTreePaths exception

The mapper will throw an exception if the root path passed into it
doesn't exist.  Catch that exception instead of crashing and just return
an empty list of PSU paths from the getPSUInventoryPath() function when
/xyz/openbmc_project/inventory doesn't exist.

This showed up due to some timing changes on an IBM system where there
aren't any /xyz/openbmc_project/inventory paths yet when this
application starts.

Tested:
When /xyz/openbmc_project/inventory isn't on D-Bus, the application no
longer crashes.
