Search result does not show store/vendor when added by Admin

[rashedripon]

Description of the bug:
If an admin adds a vendor from Dokan > Vendors > Add new the store is not found in the store-list search until the vendor saves his store settings from the dashboard.

How to reproduce:

1. Add a vendor from wp-admin > Dokan > Vendors section.
2. Search the store from the store listing page (it will show no vendor found)
3. login to the vendor dashboard and save store settings.
4. Search again on the store list page, you should get the store as expected

Expected behavior:
The store should be available on the search without the vendor needing to save the store settings.
