Prevent duplicate names in unit/integration tests

Having identical names for different test-cases may result in less helpful output, which we can avoid with the use of the ESLint Jasmine plugin.
This patch enables the rules at the `branch` level, to limit the amount/scope of the changes slightly. (We could thus make this rule more strict in the future, if that's deemed useful.)
