Renaming key to one that exists

[kashav]

RDM Version:
0.8.3.3850
Environment (OS name and version):
Windows 7
Redis Server Version:
2.4.6

Steps to reproduce:

1. Create a key with any name/value.
2. Open the key and click Rename.
3. Hit OK without typing anything (i.e. same name as before) or use a key name that already exists. You should get the following message:

Can't rename key: Key with new name already exist in database

Error is obviously expected, but keys cannot be opened anymore and reloading DB/connection does nothing. Only solution is restarting RDM.
