[TECHNICAL] Unit tests for datasources classes (providers) - Part 4

[JuancaG05]

Epic: #4063

In this issue we'll address the unit tests for the classes:

• OCSharedPreferencesProvider
• ScopedStorageProvider

Remember we want to create unit tests that check that every method returns the expected result and verify that every method calls the corresponding methods of other classes.

In addition, in this case, we'll have to discuss if moving these providers to a new package providers inside the owncloudData module since these are special datasources.
