Budget investment goes to unfeasible even when valuation is not finished

[PierreMesure]

User Story

As an admin, I want to be able to start my valuation process on one budget investment but if I deem it unfeasible, it shouldn't be displayed until the process is finished (and I check the corresponding checkbox).

Why is this Needed?

See above.

Description

Type: Bug

This is a bug because the behaviour is different for the rest of a valuation. Consul doesn't show the cost estimate or the cost explanation before ticking the box so it shouldn't move the investment to unfeasible as well.
