Adhoc Release: Fix stackoverflow crash on scan start/stop

To use this release, you must download the aar file below, and configure it with your project like so:

• Create a /libs directory inside your project and copy the android-beacon-library.aar file there.
• Configure your app's outermost build.gradle File to reference the /libs directory from above in a flatDir declaration:

      allprojects {
          repositories {
              jcenter()
              flatDir {
                  dirs 'libs'
              }
          }
      }

• Add the library AAR as a dependency, along with the Android Beacon Library like so:

      dependencies {
        compile 'android-beacon-library-2.9.2-5-gef917a1@aar'
      }
