The JcrSearchSuppliersGenerator generates a SearchSupplierDefinition for jcr apps without a configured one. However it does not set the definition name causing the message bundle key for the app name to be 'search.result.supplier..label' instead of 'search.result.supplier.appname.label' resulting in a fallback to the appname itself.

Location in the code where the definition is generated: info.magnolia.ui.framework.JcrSearchSuppliersGenerator.AutogeneratedDefinitionProvider#AutogeneratedDefinitionProvider

Location where the bundle key is generated: info.magnolia.periscope.search.SearchResultSupplierDefinitionKeyGenerator

Reproduction steps:
 0) on demo.magnolia-cms.com
 1) provide a translation for i18n key search.result.supplier.site.label
 2) search sportstation in find bar

Expected result:
 translation for key should appear in left column for results from Site app

Actual result:
 Site (as an appName fallback) appears in left column
