Store locator page broken when some countries are disabled

[sezio]

Hello

If a store exists in tthe backend for a specific country (let's say France for the example) and that we disable the country in magento system configuration, store locator page is broken

Preconditions

Magento Version : M2 CE 2.3.3-p1

Module Store Locator Version : 1.3.9.0

Environment : production

Third party modules : yes but not related

Steps to reproduce

1. Log in the backend
2. Go to Sellers > Store
3. Create a new one in France
4. Flush cache, go to frontend on the /stores page : map shows up
5. In the backend : stores > configuration > general > general > country options
6. In the allowed countries, disable the country "France"
7. Save
8. Flush cache, go to frontend on the /stores page : map does not shows up

Expected result

Map should be displayed, even with the store in disabled countries

Actual result

Map is not displayed for excluded countries in the configuration

This is broken with whatever country you choose.
Problem seems to come from the \Smile\StoreLocator\Block\Search::getMarkers function probably when loading the address.
Also, you can see that if you go see the french store in Sellers > Store after having disabled the country, the store has no country associated anymore.
