[msg7086]

Incorrect cwd after navigation tree operation.

How to reproduce:

1. Open up navigation tree panel within ftp session

2. Navigate to any folders (eg. /test/)

3. Click the small triangle expansion icon on its sub folder (eg. /test/child/)

4. Now FlashFXP will list the sub folder in the background and refresh the navigation tree view, and now current working directory in FlashFXP and remote server will differ. (eg. Client CWD: /test/, FTP Server CWD: /test/child/)

5. Press F5 to reload file listing, and it will show files under the sub folder (eg. /test/child/* appears as contents in /test/ because no CD command issued before list)
