Fix resolved artifacts over android-gradle-plugin 3.0

[litmon]

When I execute ./gradlew checkLicenses before some assemble tasks in my project, it failed.

13:47:45 :app:checkLicenses FAILED

However It succeeded after assemble task.

I fixed the issue to use resolvedConfiguration.lenientConfiguration.artifacts instead of resolvedConfiguration.resolvedArtifacts.
Because resolvedArtifacts "probably" could be allowed access after artifacts resolved. (I could not understand why it run correctly...)

test this please

https://docs.gradle.org/current/javadoc/org/gradle/api/artifacts/LenientConfiguration.html#getArtifacts--
The method only gets artefacts can be resolved. If something fails, the method ignores them. So, only succeeded artefacts remain..

https://docs.gradle.org/current/javadoc/org/gradle/api/artifacts/LenientConfiguration.html#getUnresolvedModuleDependencies--
this method returns unresolved dependencies, so I will try to add the validation it is empty.

[litmon]

When I tried LenientConfiguration.unresolvedModuleDependencies(), the returned object contains sub module project.
Sub module dependencies already got so I will ignore unresolvedModuleDependencies.

And I noticed that workaround for android-gradle-plugin 3.0( #85 ) is not necessary after using LenientConfiguration.artifacts.
I also noticed current master revision causes that ./gradlew checkLicenses succeed but ./gradlew :example:checkLicenses fail because missing libraries in licenses.yml.
So I will revert PR #85

🆒
We'll no longer need the workaround.

:note:

We should avoid https://stackoverflow.com/questions/45679847/android-studio-3-0-compile-issue-cannot-choose-between-configurations workaround, setting default like implementation project(path: ':example-dep', configuration: 'default').
