Fetch local currency on each IOU request, to ensure local currency is always up to date

[Julesssss]

Details

In the original design for Request Money & Split Bills, we were to fetch the user's local currency each time the user started the flow to ensure their local currency was always set correctly. This was once the case, but is no longer occurring.

We also need to ensure the flow can be navigated when the user is offline.

Fixed Issues

$ https://github.com/Expensify/Expensify/issues/171917

Tests

A) I ran the QA steps

B) Check the flow is not blocked when the GetLocalCurrency request fails

• I broke the GetLocalCurrency command name in Web-e
• In E.cash, I opened the IOUModal to make a request
• Although the request failed, the loading spinner still disappeared, and the flow could be navigated

C) Check the flow is not blocked when offline

• I switched off WiFi
• Opened the Request Money flow via the global menu
• The spinner did NOT block progress, and the previously set currency was used

QA Steps

• Open the app in Chrome
• Open developer tools via View > Developer > Developer Tools or CMD + OPTION + i
• Switch to the Network tab, clear the console
• From either the global nav, or DM menus, select Split Bill or Request Money
• You should see 2 Network requests in the Network tab (GetLocalCurrency & Mobile_GetConstants)
