Crashes when geolocation invoked in release

Issue

When building an application as release and signing it with a certificate, attempts to invoke HTML5 geolocation services results in an application crash.

Note, that I mean exactly HTML5 method, when you do it through navigator.geolocation

Logcat output:

Issue persists only when built as release, but not when built as debug

Same as #739, appears only when minifyEnabled in Gradle set to true

[jcesarmobile]

Going to close this one and keep #739 as the problem is minifyEnabled in both cases.
It's probably related to minifyEnabled enabling proguard, which obfuscates the code and that can make the plugin execution code not work.
