[Bug] 'New Session' does not open in correct folder for child sessions

[CWempe]

Scenario:

There are sessions in subfolders (file mode).

Like this:

• folder_A
  • Session_AA.ktx
  • Session_AB.ktx
• Default Settings

1. Open a session Session_AA which is located in folder folder_A
2. use function New Session
3. Configuration window opens with the correct folder opened.
   So I can see the Session Session_AB in the same folder.
   --> works as expected
4. use function New Session in Session of `Session_AB´
5. Configuration window opens with the root folder opened.
   So I need to open the folder folder_A manually.
   --> does not work as expected. Should behave the same like in step 3.

This is annoying when you have like five levels of sub folders and need to open them manually even if you selected New Session from a session in the correct folder.
