fix(build): Correct dependencies of cleanupAllJars gradle task

[mbektchiev]

Cloud builds started suffering from too many copies of the same JARs
because the full path of GRADLE_USER_HOME (and subsequently the full
paths to those JARs) are different with each build

[mbektchiev]

Steps to reproduce the issue with [email protected]:

1. tns create --js testCleanup; cd testCleanup
2. tns prepare android; cd platforms/android
3. ./gradlew runSbg
4. ./gradlew runSbg -i | tee build1.out -> notice that Task :app:cleanupAllJars UP-TO-DATE -this is OK since nothing has changed since the previous build was done
5. mv ~/.gradle ~/.gradle2; export GRADLE_USER_HOME=~/.gradle2
6. ./gradlew runSbg -i | tee build2.out -> notice that again Task :app:cleanupAllJars UP-TO-DATE - this is not OK and as a result you will see duplicated jars in app/build/exploded-dependencies/
7. ls -lS $(find app/build/exploded-dependencies/ -iname *.jar)

If you perform steps from 5 to 7 once again the files will be added for a 3rd time.
