1. Enable up-to-date checking in Maven plugin by default …

   Up-to-date checking has been supported for a long time. We haven't received any
   negative feedback about it. Neo4j is an example project that has up-to-date
   checking enabled to improve performance and haven't had problems with it:
   https://github.com/neo4j/neo4j/blob/6ebc409772cea13354adb6a11aab4ed38da9d53e/pom.xml#L745-L747.
   
   It should be safe to enable up-to-date checking for all users of the Spotless Maven plugin.
   
   This commit also fixes the problem where plugin execution would fail on a parent of a multimodule
   Maven project with up-to-date checking enabled. A parent project can configure Spotless as:
   
   ```xml
   <build>
     <pluginManagement>
       <plugins>
         <plugin>
           <groupId>com.diffplug.spotless</groupId>
           <artifactId>spotless-maven-plugin</artifactId>
           ...
         </plugin>
       </plugins>
     </pluginManagement>
   </build>
   ```
   
   It allows child projects to inherit plugin's version and configuration but the
   plugin is not enables by default.
   
   PluginFingerprint did not handle such configuration correctly. It could only handle a simple
   configuration like:
   
   ```xml
   <build>
     <plugins>
       <plugin>
         <groupId>com.diffplug.spotless</groupId>
         <artifactId>spotless-maven-plugin</artifactId>
         ...
       </plugin>
     </plugins>
   </build>
   ```
   
   And failed with "Spotless plugin absent from the project" error for a multimodule
   parent project with Spotless in `<pluginManagement>`.
