junit-jupiter-engine should be in dependencies to run it from Eclipse

[LorenzoBettini]

If you put junit-jupiter-engine as a dependency in surefire configuration only, then the tests can't be run in Eclipse with an exception (see below).

Note that junit-jupiter-engine is in the main dependencies section also in the official JUnit Maven example, https://github.com/junit-team/junit5-samples/blob/r5.0.3/junit5-vanilla-maven/pom.xml

I'l submit a PR shortly (only for the hello project)
