Fixing undefined data in listing flow template	NEXT-17997

Administration

Added v-if and v-else to src/Administration/Resources/app/administration/src/module/sw-flow/view/listing/sw-flow-list-flow-templates/sw-flow-list-flow-templates.html.twig to handle the render of table.
Changed routeDetailTab method in src/Administration/Resources/app/administration/src/module/sw-flow/page/sw-flow-detail/index.js to return a route object for detail tab instead of name of route.
