dev breakage tests

[abelsiqueira]

Improve the breakage tests to test a dev branch.
The dev branch can have the latest version of a package that can be considered unstable.
This is helpful when a base package, like NLPModels, makes a breaking change. All other packages can make a tentative fix and push to dev, so the breakage will show if it works.

The fix should be pushed to dev before the PR is opened, or the breakage tests have to be restarted (all of them!).
