default text input or dropdown for locations in case of skipped locations installation step

[dev-101]

Accidentally discovered issue while installing fresh Osclass 3.7.4 with geolocation step skipped.
Bender theme uses dropdowns for location by default, which will prevent posting new items unless switched to text input. It's not a big issue for experienced users, just may be confusing for some why they cannot select city from the empty list (see screenshot).
