Admin should not be able to accept invite for not registered user

[maxceem]

If we invite a user by email who is not registered at Topcoder and after we use admin user to accept such an invitation. The invitation would be marked as accepted but the member record for the user would not be created as the user is not registered at Topcoder yet.

In the code:

• In this line we change status of the invitation to accepted https://github.com/topcoder-platform/tc-project-service/blob/hotfix/project-search-sql/src/routes/projectMemberInvites/update.js#L91
• And after the query to add a member would fail https://github.com/topcoder-platform/tc-project-service/blob/hotfix/project-search-sql/src/routes/projectMemberInvites/update.js#L134

Note, that the endpoint itself would return an error, but the invitation would already be marked as accepted.
