Conflict with Guava versions

[joaquinmarquez]

When running the example test I'm getting the following exception:
java.lang.NoSuchMethodError: com.google.common.collect.ImmutableSortedSet.toImmutableSortedSet(Ljava/util/Comparator;)Ljava/util/stream/Collector;

I believe this is due to clashing versions of guava. I see in the project dependencies guava 28.1 and selenium 3.141.59 are used, but that version of selenium comes with guava 25.0.
