[TECHNICAL] Unit tests for repository classes - Part 4

[JuancaG05]

Epic:

• https://github.com/owncloud/android/issues/4063

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

• OCSpacesRepository
• OCTransferRepository
• OCUserRepository
• OCWebFingerRepository

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.
