Fix possible crash in areas that don't have offline imagery

[andreia-ferreira]

When trying to download offline imagery for an area that doesn't have this data, the app crashed with StorageException. In order to fix that, error handling was added to MogPathOrUrl.toUrl(), which was removed in the previous PR.
