Invalid containers can break dict(client) call

[klauer]

Current Behavior

Calling dict(client) when an invalid container is in the database raises an exception (and, of course, stops it from returning even a partial dictionary).

$ python -m whatrecord.plugins.happi

Possible Solution

Be more lenient about bad containers, perhaps provide information on failures even
