Currently, the `MongoDbAvailableRule` logs a warning about missed availability
of the MongoDb server and returns from the `Statement.evaluate()` making the
test not ignored but as passed
* Fix the exception handling in the `MongoDbAvailableRule` for the `Statement`
to call `Assume.assumeTrue()` instead of the plain logging to mark the test as
ignored.
This will make a JUnit test report looking correctly and also will let Sonar Cube
to report test coverage as adequate
**Cherry-pick to `5.5.x`**
