Rescue StandardError in solr indexing bl config
Rescue StandardError in solr indexing bl config

During the `hyrax:install` generator, this formerly threw a
`RuntimeError`, but recent changes in Blacklight have resulting in it
now throwing a `NoMethodError`. We want to catch *all* errors getting
the blacklight config during `hyrax:install` generation, so this
commit changes it to just rescue `StandardError` instead.
