Update team invite to work with new login/signup flow

[dahal]

• We used to have passwordless (magic link login), this PR #260 removes that flow and we are going with email/password flow.
• Team invite flow may be broken because we implemented it using magic login verificationToken.
• PR #260 has implemented password reset token flow, we could use that instead to invite the user and let invited team member setup a password.

Both of these flows are broken right now

• Invite a team member
• Invite multiple team member
