lein-parent does not honor `:mirrors` for fetching the artifact

[antonmos]

  :mirrors
  {#".*"
   {:name "my-internal-artifactory"
    :url "https://my-internal-artifactory"}}

is not sufficient to pull the library specified in :parent-project :coords

The workaround is to add

:repositories
{"my-internal-artifactory" {:url "https://my-internal-artifactory"}}
