RJS-2784: Clear internal state to avoid crashes when React Native app is reloaded

CHANGELOG.md

@@ -37,6 +37,7 @@
 * `data` and `string` are now strongly typed for comparisons and queries. This change is especially relevant when querying for a string constant on a Mixed property, as now only strings will be returned. If searching for `data` is desired, then that type must be specified by the constant. In RQL the new way to specify a binary constant is to use `mixed = bin('xyz')` or `mixed = binary('xyz')`. ([realm/realm-core#6407](https://github.com/realm/realm-core/issues/6407))
 * Fixed diverging history due to a bug in the replication code when setting default null values (embedded objects included). ([realm/realm-core#7536](https://github.com/realm/realm-core/issues/7536))
 * Null pointer exception may be triggered when logging out and async commits callbacks not executed. ([realm/realm-core#7434](https://github.com/realm/realm-core/issues/7434), since v12.6.0)
+* Fixed a bug which caused crashes when reloading React Native apps. ([#6579](https://github.com/realm/realm-js/issues/6579), since v12.0.0)
 
 ### Compatibility
 * React Native >= v0.71.4
