[FIX] - Incoming SMSs no longer clash with ongoing livechat conversations by the same visitor

[cauefcr]

Proposed changes (including videos or screenshots)

There was a data race in the defineVisitor function, causing new guests to be created even if a registered guest with that number already existed, also made sure that the open room being searched on is the correct source type, so the clash is not possible anymore.

Issue(s)

Steps to test or reproduce

LGTM!

Will a conversation coming from Widget or from an app collide with an already open room? 👀 if so, we can use this PR to discover that behavior to 🤗 and create a task for changing it

[KevLehman]

Better let's try that one outside here 👀
