Support Refaster#anyOf()

[knutwannheden]

For @BeforeTemplate annotated methods which contain one Refaster#anyOf() call we can support that by generating a corresponding number of JavaTemplates.

So far just added a test.

Noticed a small potential issue on the generated methods for Error Prone Support. For AssertJBooleanRules we now generate AssertJBooleanRulesRecipes, which includes

AbstractBooleanAssertIsNotEqualToRecipe

                final JavaTemplate before = JavaTemplate
                        .builder("#{boolAssert:any(org.assertj.core.api.AbstractBooleanAssert<?>)}.isEqualTo(!#{other:any(boolean)})")
                        .javaParser(JavaParser.fromJavaVersion().classpath("assertj-core"))
                        .build();

AbstractBooleanAssertIsTrueRecipe

                final JavaTemplate before$0 = JavaTemplate
                        .builder("boolAssert.isEqualTo(true)")
                        .javaParser(JavaParser.fromJavaVersion().classpath("assertj-core"))
                        .build();

Notice how the second form does not include any type with the matcher before templates. In the after methods those types are present.
