Refaster rules that replace TestNG assertions with equivalent AssertJ assertions

tech.picnic.errorprone.refasterrules.TestNGToAssertJRulesRecipes

Some of the classes below have TestNG @BeforeTemplates that reference wildcard type bounds (<?>), while the associated AssertJ @AfterTemplates reference stricter type bounds. This introduces the risk of producing invalid code. We do this anyway, because TestNG's wildcard types can cause javac to infer less specific types than AssertJ requires, while the appropriate (more specific) types will be inferred properly when plugged into AssertJ's API.

The following is an example of a TestNG statement, which would not be rewritten if it weren't for the wildcard matching (note that the type parameters of the map on the right-hand side will be inferred to be <Object, Object> rather than <String, Object>).

List<Map<String, Object>> myMaps = new ArrayList<>();
assertEquals(myMaps, ImmutableList.of(ImmutableMap.of()));
