Can't capitalize an state name

[Iago París]

When editing the name of a state of a node. If I try to edit from "tachycardie" to "Tachycardie" it prompts a (wrong by itself) message (image). It doesn't happen capitalizing other characters (as "tachycardiE").

[Jorge Pérez]

It is now allowed (but only when renaming the state name, not for new states)
