Keys get saved to/loaded from wrong keychain entries

When manually setting the key for a channel/nick (it is possible that a key with spaces makes this problem worse), and one of the Keychains already contains a password with an arbitrary name but with its account equal to the channel/nick, the key will be saved and later loaded from this password, possibly overwriting data from other apps.

Steps to reproduce: Manually add a password with name = "abc", account = "john", password = "123" In Colloquy do a '/setkey john "pass with spaces"' The manually added password will be overwritten.
