In JUnit4 tests when using CoreFeature - Granularity=METHOD is not working as expected

In fact because the CoreSession Guice provider is installed in scope Singleton the same session is reused even if the
Granularity=METHOD is used in tets annotations.
This can lead to weird behavior.

This can be fixed by simply replacing:

protected <T> void bind0(Binder binder, Class<T> type, Provider<T> provider)

{ binder.bind(type).toProvider(provider).in(Scopes.SINGLETON); }

with

protected <T> void bind0(Binder binder, Class<T> type, Provider<T> provider)

{ binder.bind(type).toProvider(provider); }

in class org.nuxeo.runtime.test.runner.RuntimeFeature

but should be tested before to be sure existing tests are not broken by the modification
