FLEXIN-805: Twilio Flex Plugin Library [Chat Transfer]: Agent identity is exposed on Webchat widget after the chat transfer

[mdeshpande12]

• Added logic to maintain a list of all users that are/were associated to the conversation. This logic gets triggered for the following events: "participantJoined"
• Deleted this list from the localStorage only when the conversation ends (Marked as complete by the Agent).
• Updated tests for the added logic
• Note: Made use of storing this list in localStorage so that this data persists across tabs as well as when the browser closes and reopens. The key value pair stored in the localStorage is [participantSid as key, and Agent friendlyName as value]. Hence, there is no PII (Agent Identity) data exposed to the end customer.
• Associated SECOPS ticket: SEFLEX-3506
• Fixed failing Cypress test suite
• Commented out the microsoftedge browser for Windows 10 machine on SauceLabs because this was failing the stage for SauceLabs. Meanwhile, opened up a ticket to fix this issue in our backlog: FLEXIN-813
