Using the plugin to upload an .aab file + a corresponding symbols.zip does not work.

The main reason for this is that the currently used library to parse the AndroidManifest.xml fails to correctly do so for .aab files, as the file structure is a little bit different.

To test this, simply add '.aab' extensions to 'symbolUploadRequest' and try to upload an .aab including symbols. It will fail at the call 'ApkParsers.getMetaInfo' in AndroidParser.java
