Update OC to be compatible with latest version (2020) of JSON

[jlittle-tsg]

Overview

• OC is currently using json-20090211.jar. Alfresco 7 uses a a later version of JSON (json-20200518.jar) that beats out OC.
• OC should be compatible with this version of JSON.
• In JSON 2009, JSONObject#getString() will return a stringified version of an object regardless of type. In JSON 2020, JSONObject#getString() is type safe meaning we will encounter an error if the key does not map to a string value. This is causing OC to break in multiple spots, most notable when creating ActiveWizard forms.

Solution

• Change ever occurrence of JSONObject#getString() in OC to JSONObject#get().toString()

Closed with OC commit #26713

JSON COMPATIBILITY - updating version of JSON jar brought in by core build.gradle.

As a result of this, some changes needed to be made to the way we pull string values from JSON objects. In JSON 2009, JSONObject#getString() will return a stringified version of an object regardless of type. In JSON 2020, JSONObject#getString() is type safe meaning we will encounter an error if the key does not map to a string value. This is causing OC to break in multiple spots, most notable when creating ActiveWizard forms.

This commit will change every occurrence of JSONObject#getString() to JSONObject#get().toString()
