Issue deleting folders recursively

[Sergio Villar Senin <svillar igalia com>]

Hi,

I saw some problems when deleting folder recursively. For example, it 
seems that if you have

Account
|
->A
   |
   -> B

when you try to delete A, it first tries to delete B. Even if B was 
successfully deleted when A is in its recurse_remove method, the 
get_folders call still returns B as a subfolder (maybe a refresh is needed?)
