Subject: [PATCH] Fix launch studies with empty solver (#2523)

By default, the "solver" field is empty. So the command line looks like
this

```
antares-solver --progress "029 Pumped storage" --solver=
```
which is invalid. Unless the user provides a solver, don't append
"--solver=<solverName>" at the end of the command line.
