Suppress bare repositories in RepositorySearchDialog
When a bare repository is selected in the GitSelectRepositoryPage, the
import wizard throws and reports multiple NoWorkTreeExceptions.
Since a bare repository has no working tree, one cannot import from a
bare repository. Therefore, suppress bare repositories in the
RepositorySearchDialog which is used to add repositories to the
GitSelectRepositoryPage when used from the GitImportWizard. The
user thus cannot select a bare repository.
