A short context timeout makes some tests flaky, but making it longer across the board would unnecessarily make test runs longer. Let's make it customizable per test case.
The flakiness is a result of a 100 miliseconds not always being enough time to dispatch the action in the test environment. The correct way to fix this issue is to run the assertions in an `assert.Eventually` with a longer timeout. Unfortunately, a deficiency in the `testify` testing framework makes it impossible to put the `AssertExpectations` methods in an `assert.Eventually` or `assert.EventuallyWithT` function: stretchr/testify#1414. The workaround is to increase the context timeout for the `gateway actions passed` test case. I'm increasing it from 100ms to 200ms.
