Fixes EddyVerbruggen/nativescript-plugin-firebase#1728, which seems to have been due to thread switching in the callback at FIRFunctions.m#L187. This issue will affect any native library functions called with a JavaScript object which are then wrapped in a DictionaryAdapter, and then attempt to access or enumerate the DictionaryAdapters contents from another thread.
