Fix gitlab-rake gitlab:import:repos tasksh-fix-import-repos

Because of a change in GitLab 9.5.4 to prevent users from assuming control of
a repository already on disk, the import task broke. Imports would fail with
the message, "There is already a repository with that name on disk".

This change skips the validation when the import is done from the
command-line.

Closes #37682
