Only find candidates that can't be built if there is no solution #245

We found this issue while pairing that we should only look at rejected solutions when there is no selected solution. In a scenario where there is 1 selected candidate that builds with dune and all others don't build with dune this would produce a wrong error.

Yes, I think it is better. Writing changelogs from a user perspective is quite hard when you look too much at the code. Thanks for the improvement! |

CHANGES: ### Added - Add opam extensions `x-opam-monorepo-opam-repositories` and `x-opam-monorepo-global-opam-vars` to make `lock` fully reproducible. (tarides/opam-monorepo#250, tarides/opam-monorepo#253, @NathanReb) - Show an error message when the solver can't find any version that satisfies the requested version constraint in the user's OPAM file (tarides/opam-monorepo#215, tarides/opam-monorepo#248, @Leonidas-from-XIV) - Allow packages to be marked as being provided by Opam and not to be pulled by `opam-monorepo`. To control this a new optional Opam file field, `x-opam-monorepo-opam-provided` is introduced. Its value is a list of package names that are to be excluded from being pulled (tarides/opam-monorepo#234, @Leonidas-from-XIV) - Show an error message when the OCaml version of the lock file does not match the OCaml version of the switch (tarides/opam-monorepo#267, tarides/opam-monorepo#268, @Leonidas-from-XIV) - Generate a `duniverse/README.md` file to explain the basics of `opam-monorepo` in the vendored directory (tarides/opam-monorepo#272, tarides/opam-monorepo#274, @Leonidas-from-XIV) - Add a `--prefer-cross-compile` flag for the solver to select cross-compiling versions of packages when available. This is determined through the presence of the `"cross-compile"` tag in the opam metadata. ### Changed - Bump lockfile version to 0.3 (tarides/opam-monorepo#285, @NathanReb) - Mark packages to be pulled by opam-monorepo with the `vendor` variable so using OPAM with `opam install --deps-only --locked .` will not install packages that will be installed with `opam-monorepo pull` (tarides/opam-monorepo#237, @Leonidas-from-XIV) ### Deprecated ### Fixed - Fix a bug where a package which had a single version that built with dune and got selected by the solver would be reported has having no version building with dune. (tarides/opam-monorepo#245, @Leonidas-from-XIV) - Fix the solver so it does not select beta versions of the compiler unless forced to by version constraints or `--ocaml-version`. (tarides/opam-monorepo#269, @NathanReb) ### Removed - Drop support for lockfile versions 0.2 and lower (tarides/opam-monorepo#285, @NathanReb) ### Security
