No reload function in virtual folders

[francescoGiargoni]

RDM Version: 0.9.0.684
Environment (OS name and version): Windows 10 Pro
Redis Server Version: 3.2.11

Steps to reproduce:

1. Open any DB

2. Open Any Folder

3. No option to partially reload

Expected result:
In 0.8 versions a partial reload limited to the "virtual" folder was available by right-clicking on the given folder.
I found it pretty helpful.

Actual Result:
No option available.
