The technique creation form validation doesn't check if the technique name starts with an invalid character.
Currently, if we create a technique which its name starts by an invalid character like :
one notification informs us that we managed to create this technique and it appears in the list at the left of the screen.
But in fact, if we refresh the page, this technique does not appear because it was not created.
We should check if the technique name is valid before allow user to validate the form to prevent this.
