Pi-Hole Log exception with trace

[HarvsG]

Proposed change

As seen in the related issue and discussed in the library the parent exception that is caught here sometimes does not have a message string, creating a confusing error message [homeassistant.components.pi_hole] Unexpected error connecting to Pi-hole v6 API at http://n.n.n.n:80: Cannot authenticate with Pi-hole: . Trying version 5 APIat least if the stack trace is preserved we may get some more useful logs.
