Improve ODK-X Services Test Coverage: Write Test for FormsProvider class in the Forms package

[asamiami]

The FormProvider class extends ContentProvider. This class manages access to the database.

1. In onCreate method. I would love to test to ensure it creates the right directory.
2. In the extractUriFeatures method, I would love to test ensure that the method properly extracts appName, tableId, formId, and numericFormId from the URI segments.
3. In the query method, I would love to test to :

• Ensure that the method executes the correct SQL query based on the URI structure.
• Verify that the Cursor returned from the query contains the expected data based on the projection
• Confirm that the URI is parsed correctly, and the appropriate query is executed

These tests aims to increse test coverage of ODK-X services.
This issue addresses #504

I will suggest we work on #507 first, as that is more beginner friendly, before working on this. But if you feel confident, you can go ahead :)
