[Windows] Can move file to read-only folder

1. Install Nuxeo 7.10 (tried with HF22)
2. Install Drive client (tried with 2.1.1221)
3. Server-side: Administrator creates userA
4. Server-side: Administrator create userB
5. Server-side: UserA creates 2 folders in his personal workspace (folder1 and folder2)
6. Server-side: UserA gives Edit permission to userB on folder1
7. Server-side: UserA gives Read permission to userB on folder2
8. Client-side: UserB synchronizes the data
9. Client-side: UserB creates a text file named myFile.txt in folder1 and waits for synchronization to finish
10. Server-side: double-check the file has been created
11. Client-side: UserB moves myFile.txt from folder1 to folder2
12. Client-side: wait for synchronization to finish

Result: there is nothing in the client log stating that folder2 was read-only but the file was actually moved. Server-side myFile.txt remained in folder1 so this is the expected behavior. But client side there were neither a rollback putting back the file in folder1 nor a notification saying that folder2 was read-only.

Expected result: either a notification should pop-up or myFile.txt should be put back in folder1. In both cases there should be something specific in the logs.
