I think is better if you remove all data about this server when delete it on ServerDropdown.. like the database, RNUserDefaults info and the serverRecord on serversDB.

@CalebeRios I've fixed unnecessary changes, warnings and an if condition on this PR.
Can you fix the delete method?

On RocketChat.logout, we have this delete steps implemented already: https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/develop/app/lib/rocketchat.js#L342
You could move part of the logic to a new method called removeServer and call it on logout and on ServerDropdown.

Thanks for changes @diegolmello. I will see the changes you made and finish that issue. My problem is to delete the database, because in logout we delete the active database, and I need get the database of another server. Can you give me a light?

[diegolmello]

@CalebeRios Ok.
You should do something similar to setActiveDB, but without changing the current state.
Think in something like getDB, that runs a similar logic to as setActiveDB but it doesn't change this.databases.activeDB.
https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/develop/app/lib/database/index.js#L54

From there, you can receive a database obj and run an action to reset it.
