Lazily evaluate file paths for debug and instrumentation APKs

[julioz]

debugApk and instrumentationApk are using the Gradle Property API, but still being evaluated in the configuration phase, preventing non-string references with the plugin configuration, for example:

fladle {
  debugApk = project.provider { findArtifactPath(some, parameters, here) }
}

Is this supposed to be fixed with https://github.com/runningcode/fladle/issues/92 or is it a separate issue in the current plugin version?
