Renaming of files to a different case leads to file duplication.

[SergioBertolinSG]

Steps to reproduce

0. Enable dropbox app. (release/1.0.1).
1. Set up dropbox mount point, grant access and so on. (all ok).
2. Upload a file for example perrito.jpg.
3. Rename it to a different case combination for example PERRITO.jpg.
4. See the warning and refresh the page.

Expected behaviour

There is a warning informing that you cannot rename the file because it is already in use. (Maybe this should be more clear, saying that you are in a case-sensitive storage)

And only one file remains.

Actual behaviour

There is a warning

The name "perrito.jpg" is already used in the folder "/DropboxAPINUEVA/MAYUSCULAS2". Please choose a different name.

But it creates a second file:

@SergioBertolinSG Not sure what this could be fixed in dropbox

I'll try to keep it simple

• Consider Your file ABC.txt exists in dropbox and then you try to upload abc.txt (same file different name casing)
• ownCloud then asks the dropbox whether this file -> abc.txt exists which it does
• then ownCloud sees that this file is not present in oc_filecache but exists in dropbox so it thinks that file cache is outdated and it updates that (the reason for duplicate file)

@jvillafanez how does WND solves this problem?

See #52 for a new flysystem option.

I doubt this will fully solve the issue but might be worth a try
